[python311] Update to Python 3.11.0b2

[The-Compiler]

See Mailman 3 [RELEASE] The second Python 3.11 beta (3.11.0b2) is available - Python-announce-list - python.org.

Built locally and it seems to work.

Hm, how do you feel about including python/cpython#93397, a fix for python/cpython#93387? Unfortunately, the fix didn't make it into b2, and without it, pytest seems unusable.

[The-Compiler]

So b2 is already in master via 421fd48, but b3 is out already with a fix for this: Mailman 3 [RELEASE] Expedited release of Python3.11.0b3!! - Python-announce-list - python.org

I'm pretty sure I updated to b2 within a few hours of the release announcement 😄
