Add python 3.13.0-rc.1 to CI in prep for real 3.13 release

[benclifford]

This usually flushes out various incompatibilities in both parsl and dependencies - which I'll hack out of the tests in order to find the next set of breakage.

Type of change

• New feature

This fails on greenlet. There is some discussion about getting greenlet working on 3.12 here: python-greenlet/greenlet#396

greenlet is needed for sqlalchemy which is needed for parsl[monitoring], so this dependency isn't blocking no-monitoring parsl.

@AymenFJA and @andre-merzky - radical pilot is failing import with Python 3.13 release candidate 1, in our CI. I think this is a general radical pilot problem, not specific to the parsl/radical integration.

This method disappeared in python/cpython@74723e1

cc parsl issue #2343 which is a general tracker for this kind of fork related issue.

Thanks @benclifford , I'll have a look at this ASAP.

[andre-merzky]

Yes, some monkeypatch we do on logging is not needed anymore, thanks for the ping! This will be fixed in the next release. How urgent is that for you @benclifford?

Ideally, Parsl would work with Python 3.13 on release day, 2024-10-01, https://peps.python.org/pep-0719/ but that is not a hard requirement, and right now greenlet (see earlier in this PR) is a more serious problem.

[benclifford]

re greenlet, python-greenlet/greenlet#396 was merged a few hours ago, so next step there would be watching it propagate into releases
