python3-Babel: update to 2.12.1.
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### 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 https://github.com/python-babel/babel/pull/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`.
