There are two checks that are expected and required,
but will never run,
because I re-named them...

I will have to update the branch protection to require:

• Continuous Integration tests / upstream-py311 (nocmk)
• Continuous Integration tests / upstream-py311 (test-upstream-requirements-py311)
• Continuous Integration tests / upstream-py37 (test-upstream-requirements-py37)
• Continuous Integration tests / upstream-py37 (nocmk)
