Replace `isort` with `ruff`?

[art3xa]

ruff.isort can replace isort (https://docs.astral.sh/ruff/faq/#how-does-ruffs-import-sorting-compare-to-isort)

Agree it would be nice to just use ruff and have faster import sorting.

Info how to apply it is here mentioning that there's still some plans to improve isort via ruff:

• https://docs.astral.sh/ruff/formatter/#sorting-imports
• https://www.directedignorance.com/blog/ruff-sorting-imports-with-pre-commit

Would PR to try and apply it now be useful or better wait?
