Dominik Schilling d8357b76c5 Upgrader: Don't use Language_Pack_Upgrader_Skin::before() and Language_Pack_Upgrader_Skin::after() when translations are up to date. ...

Avoids a PHP notice since `Language_Pack_Upgrader_Skin::before()` tries to access a non-existent update.
Also, change the `up_to_date` string to use the plural form because translations are only updated in bulk mode.

Fixes #36615.
