 I am editing the title and description of this PR:
- It should be "Lint code" instead of "Format code": formatting was still done with `black`
- This PR uses `ruff` instead of `isort` and `flake8` (not `black`): note that `black` was still used for formatting
EDIT:
Use `ruff` for linting instead of `isort` and `flake8` ~~`black`~~ to be consistent with [`transformers`](https://github.com/huggingface/transformers/pull/21480) and [`hfh`](https://github.com/huggingface/huggingface_hub/pull/1323).

TODO:
- [x] ~Merge the community contributors' PR to avoid having to run `make style` on their PR branches~ (we have some new PRs, but fixing those shouldn't be too big of a problem)
