Chore: Ruff pycodestyle warnings

[iLLiCiTiT]

Changelog Description

Added pycodestyle warnings to ruff selection.

Additional info

Warnings contain complains about trailing spaces, new line characters etc.

Testing notes:

1. Validate the changes.

[BigRoy]

Admittedly I know nothing of the validation error numbers, etc. But this does look like it'd select more and hence be stricter - so I'll give it a thumbs up.

But if you have any good pointers on how to accurately confirm it does what we want, let me know.

It looks like actions can't run in template repositories. I did run it manually (create venv, activate venv, install ruff, run ruff check in root of repository).
