What's the problem this feature will solve?

Currently for regular PRs pip only tests against the oldest supported Python version and the newest supported Python version:

But when pip does a final release I think it would be reassuring for all versions of Python to be tested against.

Describe the solution you'd like

Somehow in the GitHub workflow file have a condition that runs all untested versions of Python for the final release.

Alternative Solutions

Do nothing.

Additional context

I don't know how to implement this yet, but if no one else does this I plan to spend a bit of time investigating this in the future and raise a PR. I'm guessing have a job associated with a specific path filter on NEWS.rst that tests these versions of Python on Windows.
