LGTM.
-> Do we need to test pypy3.10?
-> Bring back the drop 3.9 support ticket. (Just referencing this PR in it should suffice)

Do we need to test against pypy3.10 as well?

It felt odd to leave it out, putting it in the bucket of EoL versions that should still work.

Should we make "Drop 3.9 support" a python ticket? (Or re-open it?)

PYTHON-5670
Changes in this PR
Restores support for PyPy 3.9, PyPy 3.10, and Python 3.9.
Since all of these versions are EoL, we do not test against all scenarios.
Instead we test on
latestserver with the three standard combinations of topology, auth, and ssl.We only test on one platform.
Test Plan
Added a "Min Support RHEL8" variant with 9 tasks.
Passing build: https://spruce.mongodb.com/version/6938c98cb2efbb0007254ae8/tasks?sorts=STATUS%3AASC%3BBASE_STATUS%3ADESC
