Subject: [PATCH] [I18N] Add Locale merger script

(cherry picked from commit ecc3dae2acaf567cd6b2888cc5c582588c7bfc53)
(cherry picked from commit c6c3fc6ace6b6aa4f4877c5a96da54899f2dc2fa)
(cherry picked from commit 4833bd594a49b70896c023b41da8a87ba33add0e)

[I18N] in the home page replace GitHub with Forgejo

The english string that shows on the home page to encourage for
contribution no longer reference GitHub. But some translations still
do. In this context, and this context only, replace it with Forgejo
even though it may not be correct in some cases.
