Subject: [PATCH] [I18N] Add Locale merger script (squash) abort on NOOP

If a string is no longer used in the english version of the locales,
it means the Gitea string was changed and it needs updating. Abort
when it is the case and recommend action.

(cherry picked from commit 34f3d7d65e982b729bb878dde04c8a1093885ed6)
