Although I am in general for not changing the formatting too often (as it generates huge diffs, which is the opposite of why we are using formatters in the first place), this change makes sense as it simplifies the workflow considerably.

I added an explanation of how to use pre-commit to the README and removed black and isort from the requirements.

Thanks for the update!

Two more advantages of this change:

1. We no longer need to keep the formatter versions in sync between GitHub Actions and pre-commit.yaml, avoiding potential version mismatches.
2. Switching to ruff makes both the workflow and formatting faster, since it’s built in Rust and extremely fast compared to other tools (https://docs.astral.sh/ruff/).
