Fix ruff issues

[Bouni]

I noticed that ruff was complaining after I merged a PR that was open for a few months, despite it was marked as all good in the PR view.

Probably som versin mismatch or something like that.

So I fixed the linter warnings and upgraded the pre-commit-cofig and the lint action.
