region: All input sources should be selectable irrespective of which locales have been generated

The GUI in g-c-c for adding input sources shows a selection of sources depending on which locales have been generated. This makes little sense, since any input source can be used irrespective of which locales are present, and causes user confusion.

Example I: User couldn't find the Spanish (Latin American) keyboard layout

Example II: User couldn't find the Chinese (Chewing) input method

Example III: User couldn't find the Belgian keyboard layouts

Example IV: User couldn't find any Hebrew XKB layouts (This is an additional issue which is present in at least GNOME 44, but was not present in GNOME 41.)

It does make sense IMO to make use of generated locales for the suggestions in the first window, but no input sources should be completely hidden due to the absence of a particular locale.

Please reconsider the design in this respect.
