docs: enhance contributing guidelines to be more accessible

Problem:

The contributing and development guidelines in this repository could benefit from an improvement pass to make workflows, expectations, and intentions clearer.

Solution:

Rework/refactor the CONTRIBUTING.md, DEVELOPMENT.md, GitHub issue templates, and pull request template with the goal of improving understandability to those not
familiar with the code base, hatch-based workflows, GitHub pull request workflows, and our use of conventional commits.

+A breaking change is one that modifies a public contract in some way or otherwise changes functionality of this application in a way

 ## Reporting Bugs/Feature Requests
 
 We welcome you to use the GitHub issue tracker to report bugs or suggest features.
 
 When filing an issue, please check existing open, or recently closed, issues to make sure somebody else hasn't already
-reported the issue. Please try to include as much information as you can. Details like these are incredibly useful:
-
-* A reproducible test case or series of steps
-* The version of our code being used
-* Any modifications you've made relevant to the bug
-* Anything unusual about your environment or deployment
+reported the issue. Please try to include as much information as you can.
 
 ## Development
 
-Please see [DEVELOPMENT.md](./DEVELOPMENT.md) for more information.
+We welcome you to contribute features and bug fixes via a [pull request](https://help.github.com/articles/creating-a-pull-request/).
+If you are new to contributing to GitHub repositories, then you may find the 
+[GitHub documentation on collaborating with the fork and pull model](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/getting-started/about-collaborative-development-models#fork-and-pull-model)
+informative; this is the model that we follow.
+
+Please see [DEVELOPMENT.md](./DEVELOPMENT.md) for information about how to navigate this package's
+code base and development practices.
+
+### Finding contributions to work on
+
+If you are not sure what you would like to contribute, then looking at the existing issues is a great way to find
+something to contribute on. Looking at 
+[issues that have the "help wanted" or "good first issue" labels](https://github.com/aws-deadline/deadline-cloud-for-maya/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22%2C%22help+wanted%22)
+are a good place to start, but please dive into any issue that interests you whether it has those labels or not.
 
-## Contributing via Pull Requests
+### Talk with us first
+
+We ask that you please [open a feature request issue](https://github.com/aws-deadline/deadline-cloud-for-maya/issues/new/choose)
+(if one does not already exist) and talk with us before posting a pull request that contains a significant amount of work,
+or one that proposes a change to a public interface such as to the interface of a publicly exported Python function or to
+the command-line interfaces' commands or arguments. We want to make sure that your time and effort is respected by working
+with you to design the change before you spend much of your time on it. If you want to create a draft pull request to show what
+you are thinking and then talk with us, then that works with us as well.
+
+We prefer that this package contain primarily features that are useful to many users of it, rather than features that are specific
+to niche workflows. If you have a feature in mind, but are not sure whether it is niche or not then please 
+[open a feature request issue](https://github.com/aws-deadline/deadline-cloud-for-maya/issues/new/choose). We will do our best to help
+you make that assessment, and posting a public issue will help others find your feature idea and add their support if they
+would also find it useful.
+
+### Contributing via Pull Requests
 
 Contributions via pull requests are much appreciated. Before sending us a pull request, please ensure that:
 
-1. You are working against the latest source on the *main* branch.
+1. You are working against the latest source on the *mainline* branch.
 2. You check existing open, and recently merged, pull requests to make sure someone else hasn't addressed the problem already.
 3. You open an issue to discuss any significant work - we would hate for your time to be wasted.
+4. Your pull request will be focused on a single change - it is easier for us to understand when a change is focused rather
+   than changing multiple things at once.
 
 To send us a pull request, please:
 
 1. Fork the repository.
-2. Modify the source; please focus on the specific change you are contributing. If you also reformat all the code, it will be hard for us to focus on your change.
-3. Ensure local tests pass.
-4. Commit to your fork using clear commit messages.
+2. Modify the source and add tests for your change; please focus on the specific change you are contributing.
+   If you also reformat all the code, it will be hard for us to focus on your change.
+   Please see [DEVELOPMENT.md](./DEVELOPMENT.md) for tips.
+3. Ensure tests pass. Please see the [Testing](./DEVELOPMENT.md#testing) section for information on tests.
+4. Commit to your fork using clear commit messages. Note that all AWS Deadline Cloud GitHub repositories require the use
+   of [conventional commit](#conventional-commits) syntax for the title of your commit.
 5. Send us a pull request, answering any default questions in the pull request interface.
 6. Pay attention to any automated CI failures reported in the pull request, and stay involved in the conversation.

-## Finding contributions to work on
-
-Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any 'help wanted' issues is a great place to start.
-
+### Conventional commits
 
-## Code of Conduct
+The commits in this repository are all required to use [conventional commit syntax](https://www.conventionalcommits.org/en/v1.0.0/)
+in their title to help us identify the kind of change that is being made, automatically generate the changelog, and 
+automatically identify next release version number. Only the first commit that deviates from mainline in your pull request
+must adhere to this requirement.
 
-This project has adopted the [Amazon Open Source Code of Conduct](https://aws.github.io/code-of-conduct).
-For more information see the [Code of Conduct FAQ](https://aws.github.io/code-of-conduct-faq) or contact
-[email protected] with any additional questions or comments.
+We ask that you use these commit types in your commit titles:
 
+* `feat` - When the pull request adds a new feature or functionality;
+* `fix` - When the pull request is implementing a fix to a bug;
+* `test` - When the pull request is only implementing an addition or change to tests or the testing infrastructure;
+* `docs` - When the pull request is primarily implementing an addition or change to the package's documentation;
+* `refactor` - When the pull request is implementing only a refactor of existing code;
+* `ci` - When the pull request is implementing a change to the CI infrastructure of the packge;
+* `chore` - When the pull request is a generic maintenance task.
 
-## Security issue notifications
+We also require that the type in your conventional commit title end in an exclaimation point (e.g. `feat!` or `fix!`)
+if the pull request should be considered to be a breaking change in some way. Please also include a "BREAKING CHANGE" footer
+in the description of your commit in this case ([example](https://www.conventionalcommits.org/en/v1.0.0/#commit-message-with-both--and-breaking-change-footer)).
+Examples of breaking changes include any that implements a backwards-imcompatible change to a public Python interface,
+the command-line interface, or the like. 
 
-We take all security reports seriously. When we receive such reports, we will 
-investigate and subsequently address any potential vulnerabilities as quickly 
-as possible. If you discover a potential security issue in this project, please 
-notify AWS/Amazon Security via our [vulnerability reporting page](http://aws.amazon.com/security/vulnerability-reporting/)
-or directly via email to [AWS Security]([email protected]). Please do not 
-create a public GitHub issue in this project.
+If you need change a commit message, then please see the
+[GitHub documentation on the topic](https://docs.github.com/en/pull-requests/committing-changes-to-your-project/creating-and-editing-commits/changing-a-commit-message)
+to guide you.
