This is ready for review, but it's on top of #42 to avoid CI failures based on docs.

This refactoring updates CI, decreasing redundancies, adding increased testing (doc and spell testing), while decreasing CI runtime by approximately 50% (up to 75% for some runs).

New configuration for git logs and CodeCov is also included.

Other minor changes are included so that the new CI tests all pass.

I make it ready, and rebase it on 'main', when #42 is merged.

@sylvestre , @tertsdiepraam

Once this is merged, I'll post a draft PR that has the 100% code coverage refactor.
I'm interested in both of your opinions on it.
It adds a lot of testing flexibility, but at the cost of some boilerplate and a lot of secondary dependencies.

@rivy maybe 2.1.0 for the next release ? :)
