Subject: [PATCH] XWIKI-13967: Confusion between Supported Languages and
 Default Languages when multilingual is set to no (#2770) (#2805)

* Added a CSS ruleset to remove the supported languages field from the UI when it's not useful.

(cherry picked from commit fcb46996b8fdebc9a01063786cdca95c167ddd29)
