Replace `prospector` with `ruff` integrated in Codacy

[valeriupredoi]

This is the sister issue of the Tool one ESMValGroup/ESMValTool#3739

As of 5 March 2025, the codacy-ruff app is live https://github.com/codacy/codacy-ruff

@bouweandela has already started ruffling up the source code to comply with Ruff standards, we still have to get Ruff integration in Codacy - please monitor the Tool issue linked above for progress on that front 🍺

Hi @valeriupredoi ,

The code freeze for version 2.12 is scheduled for next week on Feb 11th. Will you have time to address this issue for this release? If not, let me know and I will move it to the next milestone.

thanks Saskia, this still needs the Codacy app to be accepted and integrated into Codacy - fairly slow progress on that front, last I heard this will happen in Q1-2025, so I moved the Milestone

may have to reopen if #2683 didn't really do the trick

it's alive and enabled!! 🥳

This is really great progress, but we have not yet replaced prospector by ruff. So far we have replaced flake8 by ruff. To fully replace prospector, we will need to enable all the ruff rules that represent tools that are part of prospector, most notably pylint.
