Use ruff for formatting

[tqa236]

Description

• Use ruff for formatting
• Use pre-commit instead of tox to run linting and formatting task.

I took the liberty to combine both changes into 1 PR as they are quite short, especially the replacement of tox by pre-commit

Checklist:

• I have updated the documentation in the README.md file or my changes don't require an update.
• I have added an entry in CHANGELOG.md.
• I have added or adapted tests to cover my changes.
• I have run tox -e fix-style to format my code and checked the result with tox -e style.
