Adds test coverage data

This is ready for review.

If you want to complete the coverage enablement, try to also upload the data to codecov.io -- You can inspire from https://github.com/ansible-community/ansible-compat/blob/main/.github/workflows/tox.yml#L217-L222 -- it is a little bit dated but still works.

I will enable codecov integration and we will see jobs reporting when coverage goes down.

I will try to add the according workflow steps.

I will look into this a bit later this week.

I will look into this a bit later this week.

No hurry, fixing stuff in small steps is the best approach as we never know how much time we have available. I mentioned that only for follow-ups, it was not a required for enablement.

Still, this needs to report green to merge it.

Cannot really review if CI is reporting red.

I'll revert 9387334 for now and will add this via it's own PR later on.
