We discussed this at length while producing this wiki page:

https://github.com/SciTools/.github/wiki/Linting

We agreed that we preferred to keep everything within pyproject.toml

If this is merged, some updates will be needed to the text of #5625

Note this PR has actually actioned MORE of the desirable files than expected, due to a temporary mistake in my pre-commit configuration.

Later on we need to explore improving the pre-commit file filters, as the current ones in the template are too restrictive when it comes to non-Python files. But the scope of this pull request is already quite wide, so I would prefer not to do so here. If the reviewer is happy I will raise an issue against the main template in SciTools/.github.
