greenlet fails under python 3.11.8

[gmweinberg]

I am getting an error with pip install -r requirements-dev.txt under python 3.11.8
The error starts out
In file included from src/greenlet/greenlet.c:11:
src/greenlet/greenlet.h:42:5: error: unknown type name ‘CFrame’
42 | CFrame* cframe;
| ^~~~~~
src/greenlet/greenlet.c: In function ‘green_clear_exc’:
src/greenlet/greenlet.c:173:17: error: ‘_PyErr_StackItem’ {aka ‘struct _err_stackitem’} has no member named ‘exc_type’

I was able to make the error go away by removing the version number in requirements.txt, the installation seems to work with greenlet==3.0.3

Hmm, I see my pull request is failing under the test system. If I'm reading it correctly, the error is
ImportError: cannot import name 'Celery' from 'celery' (/opt/hostedtoolcache/Python/3.7.17/x64/lib/python3.7/site-packages/celery/init.py)

I admit I only tested under python 3.11 but it seems to me that since 3.7 is past its expiration date it really doesn't need to be supported for new installs. Also, if you'll forgive my naivate, I really don't understand how updating the greenlet version would cause celery to break.

I can't disagree. If you can come up with a PR that removes dead versions of Python too that'd be awesome :-)

I'll give it a shot. It looks like I just need to change .github/workflows/tests.yml
