chore: include storage-py into monorepo

[o-santi]

What kind of change does this PR introduce?

Add storage-py to the monorepo.

Additional context

• Add it as an entry to the workspace in pyproject.toml
• Copy the relevant files to src/{project_name} (including CHANGELOG.md, LICENSE and Makefile!)
• Use the package directly from workspace in src/supabase, instead of from pypi.
• Add its tests to the main Makefile, and the directory itself to make publish.
• For projects using unasync-cli, switch away from it.
• Add it to release please
• Add it to main README.md

In order to make supabase cli work with multiple projects, I manually altered both src/storage/tests/tests.env and src/storage/infra/supabase/config.toml to use different ports for the project. I chose ports starting with 55 instead of 54 as used in realtime, and intend to keep this pattern for the other two packages remaining (56 and 57).

Also, storage/tests/_async as they were did not work with pytest-asyncio >= 0.21.2 (required by the other packages), even though it was marked as working, due to its heavy usage of fixture scopes and its interaction with event loops. Thusly, I temporarily removed all scopes and the event loop special casing, and we can consider re-introducing it in the future if it is needed. As far as I understand, they are simply a performance improvement, and aren't needed for test correctness. If this assumption is wrong, please let me know.
