[TASK] Add information about Test Runners, with their advantages and disadvantages

[garvinhicking]

This is a larger (not-yet-proofread) chapter on the topic of Test Runners. I feel this has often been a topic in the community, and the current improvements on documenting testing rectify being more verbose on this.

I propose to merge this and iterate on it with followup-PRs, if the basis of this PR is agreeable.

I've requested a few reviews for this because I'd like to have everyone involved on-board with this, I hope that's ok.

I think the content is a great starting point and can be improved successibly! Thanks for writing this down!

I've read through the whole PR and like the idea and way you go. I guess the list of advantags an disavantages is never finished and everyone might have his or her own thoughts about that. So this is a great starting point and might help people to get to know the possibilities.

Thanks for your efforts.

git push --set-upstream origin backport-4554-to-11.5
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-11.5

Then, create a pull request where the base branch is 11.5 and the compare/head branch is backport-4554-to-11.5.
