Generate templates from recipes

[chrisvxd]

The code in /recipes and /packages/create-puck-app/templates is currently duplicated. We should reconcile these to prevent users from committing changes to the wrong directory. See #120 for example.

Solution

Suggest we should add a script that either:

1. (Preferred) Generate the template from the recipe, as recipes are the logical entry point for people to make changes.
2. Generate the recipe from the template

Considerations

• If going with option 1, preserve the handlebars template files (package.json, anything else)
• Add a CI check to make sure there is no diff (run the script and check for working changes. None should be present)
