Refactoring around add-on store Repository classes (#5990)

* Rename repository fixture to test_repository

Also don't remove the built-in repositories. The list was incomplete,
and tests don't seem to require that anymore.

* Get rid of StoreType

The type doesn't have much value, we have constant strings anyways.

* Introduce types.py

* Use slug to determine which repository urls to return

* Simplify BuiltinRepository enum

* Mock GitRepo load

* Improve URL handling and repository creation logic

* Refactor update_repositories

* Get rid of get_from_url

It is no longer used in production code.

* More refactoring

* Address pylint

* Introduce is_git_based property to Repository class

Return all git based URLs, including the Core repository.

* Revert "Introduce is_git_based property to Repository class"

This reverts commit dfd5ad79bf.

* Fold type.py into const.py

Align more with how Supervisor code is typically structured.

* Update supervisor/store/__init__.py
