CI: fix pre-commit warnings/errors in linting

[nilason]

Address pre-commit warnings and fixes. A majority of the issues originate from CI bot PRs, but not all.
This emphasises the need to explore the introduction of pre-commit.ci.

If there are no objections I'll take the liberty to merge this "whitespace" fix.

It breaks the output of the warning, but that warning was written by me to intentionally mentioning that the test failures must be fixed one day to upgrade the package version.

It can stay as is!

I don't have any deciding powers, but I still approve these changes :)

The warning is there:

Successfully installed pytest-pylint-0.19.0
Warning:   Temporarily downgraded pytest-pylint to allow merging other PRs. The errors reported  with a newer version seem legitimite and should be fixed (2023-10-18,  see https://github.com/OSGeo/grass/pull/3205)
============================= test session starts ==============================

with colours and all.

It is the extra spaces in between some words that come from the new indentation. But either way, the goal is to have it removed some day, so it doesn't matter at all.

Yes, there is one extra space after warning. But the warning is issued correctly. Multiline strings in yaml is a PITA.

I will update this after #3254 is merged.
