Add PR Template and General Issue Template

[samriddhi99]

It would be helpful to add the following templates to this repository to ensure consistency and improve the quality of both PRs and issues:

1. Pull Request (PR) Template:

A PR template will guide contributors to provide the necessary information when opening a PR, such as:

• What changes are being made
• Why the changes are necessary
• What effects those changes have
• Any related issues or tickets
• Testing

It is also recommended to have a checklist that looks like this:

• Checklist:
  • Code has been linted.
  • Documentation has been updated (if needed).
  • Tests have been added or updated (if needed).

2. General Issue Template:

Tirith already has templates for bug reports and feature requests. It would be useful to introduce a general issue template for cases that don't fall into either of those categories.

The template should include:

• Provide a detailed description of their issue.
• Outline any expected or unexpected behaviors observed in the code.
