Doc: |today| format does not honor language's time format

[rffontenelle]

The Sphinx |today| variable in Python Docs is rendered in the English time format "month day, year" even when browsing in other languages. This is mostly (or only?) noticeable in What's New in Python, e.g. 3.11.

I'd expect the date to honor the language's time format as translated in Sphinx. Taking version 4.5.0 which is used to build Python Docs 3.11, pt_BR and fr are translated to show "day month, year".

The source of this issue seems to be in Doc/conf.py which sets today_fmt's value, hence overriding Sphinx default value and its translations.

Steps to reproduce:

• Browse original What's New in Python 3.11 and see Date: March 29, 2023
• In the language drop-down menu, select Brazilian Portuguese and see Date: março 29, 2023 where should be 29 março, 2023
• Now select French, see Date: mars 29, 2023 where should be 29 mars, 2023

The |today| variable has been removed from the What's New pages, for example see:

• "What's New In Python X.YZ" Pages Show Incorrect Release Information #100700
• [3.11] gh-100700 Remove Date and Release fields in past whatsnews (GH-100728) #106999

And we can see it's been removed from the pages:

• https://docs.python.org/3.11/whatsnew/3.11.html
• https://docs.python.org/fr/3.11/whatsnew/3.11.html

Therefore we can close this. Thanks for reporting!
