python3-Babel: update to 2.12.1.

[tornaria]

Testing the changes

• I tested the changes in this PR: briefly

Using sphinx with current version of python3-Babel gives the following deprecation warning :

$ python -Wonce -c 'import sphinx.application'
/usr/lib/python3.11/site-packages/babel/messages/catalog.py:13: DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13
  from cgi import parse_header

The update fixes this. I had to include python-babel/babel#998 so tests pass, since it only touches test code I think its safe to include.

I found this while doctesting sagemath. A bunch of tests fail because of this deprecation warning, and after this update everything passes.

Cc: @sgn, since this affects python3-Sphinx.

For the record: pytz is no longer a dependency, if not installed zoneinfo will be used. However, there is some subtle discrepancy in behaviour between the two which causes a couple of test failures (reported upstream: python-babel/babel#988 (comment)).

Since this is not just test failures but an actual change of behaviour, I'd propose to keep pytz as a dependency for consistent behaviour while this is sorted out upstream.

I would argue that the new behaviour is more correct :D

Anyway, this could fix the test:

The 998 patch is no longer needed, too.

Done, thanks.

@sgn: anything in particular holding this back?

I would like to merge #43225 which needs (and includes) this PR.
