Nice! I still have some comments.
Also, please add a commit that makes pre-commit run --all-files pass.

In a different PR. This one is big enough as it is. What is more, the option --from-ref ${{ github.event.pull_request.base.sha }} --to-ref ${{ github.event.pull_request.head.sha }} in the Github action makes pre-commit only run on the changes and not all files (which is more useful IMHO)
