Translations are provided by .directory files, so trying to look up a category name without the suffix will always fail. Commit 343b3351f1 tried to fix this previously by changing the saved keys, but that broke existing translatable folders. Appending the .directory suffix for the lookup instead fixes the issue without regressing non-custom folders. https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2623
