Reconsider PyPy 3.7, and 3.8 removal in 0.23.x series

[Ousret]

Hello,

I am writing to ask for a revert of recent change introduced in 0.23.x releases.
The change I am referring to is located at #4582

I far as I can understand, no API / Bridge change occurred in the PR. No code simplification occurred, only the check for minimal version was patched.

While this change appear straightforward, it induce friction for integrators.
We want to publish new versions, but we are stuck/embarrassed due to the high level constraint (namely python_requires >= 3.7). There is no easy way to mark PyPy 3.7 and 3.8 excluded defacto so that pip or alike wouldn't pick the newer version.

I also understand that the change was motivated due to CI flakyness.

My proposal is as follow:

• Revert the change drop support for PyPy 3.7 and 3.8 #4582
• Add a warning that PyPy 3.7, 3.8 might not work, not tested upstream any more. due to constraints in PyO3 developments. Use at own risk.
• Remove CI pipelines for them OR marks them as success anyway (ignore non-zero exits).

This would be greatly appreciated.
Regards,
