Title:
  date does not support localized output

Bug description:
  Hello Ubuntu,

  On the new Ubuntu 25.10, the "date" command fails to print locale
  names:

    LC_TIME=tr_TR.UTF-8 date +%B 
  prints: 
    November 
  instead of:
    Kasım, 

  This command was OK on Ubuntu 24 (used inside a script to Grep month
  names from a CSV file written in Türkish.

  This command fails with the Rust version of coreuils.

  Note however that the "locale" config is correct as the following command works as expected:
    locale -k LC_TIME 
  shows the good locale name 
    ...
    mon="Ocak;Şubat;Mart;Nisan;Mayıs;Haziran;Temmuz;Ağustos;Eylül;Ekim;Kasım;Aralık"
    ...

  Do I need to switch back to the old C based coreutils package?
  Thanks to give a solution... 

  There is no emergency however as I have added the English month names
  in my CSV file... so my command works again... Just tried to inform
  you about this behavior that seems to not be documented on Internet, I
  googled for a valid answer, found nothing.

  Thanks to give a solution. Also, some apps like Shotcut, Gimp crashes
  on Wayland (but works on X11 reinstalled automatically by the Budgie
  Desktop). The latest Shotcut as an Appimage seems to work on Wayland,
  but I want a real App installed normally withou Snap or Flatpak or
  Appimage.
