Test Python 3.12 support

[pquentin]

I'm trying to add support for the Python 3.12 betas in elastic/rally#1730, but am hitting this error:

This is unlikely to be enough, according to a comment below there are APIs in Python 3.12 to do that now?

Your own CI is blocked by python-greenlet/greenlet#327

[pquentin]

@sumerc greenlet has issued a pre-release with Python 3.12 support, which fixed yappis's CI. You can see the tests passing here with greenlet 3.0.0a1 and my changes: https://github.com/pquentin/yappi/actions/runs/5440881956/jobs/9894253241. What do you think?

Note that GitHub Actions no longer supports Python 2.7, are you ready to drop support? I can do that in a different pull request.

I submitted the PR #145 to remove support of Python2.7

[joelcapitao]

Hi @pquentin
I wrote some minor comments

Cheers

[joelcapitao]

I think those removals should be included in another PR.
And we should remove those lines [1] and adapt [2] as well.

[1] https://github.com/pquentin/yappi/blob/dff6a39973a643a128338d4dae94c846c0072b5d/run_tests.py#L25C1-L26C34

[joelcapitao]

This can be remove once the PR rebased on top of #145

Thanks for the review. However this was more a proof of concept and I have a lost interest since then. Feel free to reuse my pull request, it has the same license as the code itself. Thanks again!
