 In [changeset:"55229" 55229]:
 {{{
 #!CommitTicketReference repository="" revision="55229"
 Upgrade/Install: Send language pack updates to `copy_dir()`.

 If the `clear_working` flag in `WP_Upgrader::install_package()` is false,
 the source should not be removed, so `copy_dir()` should be used instead.

 Partial updates, like language packs, may want to retain the destination.
 If the destination exists or has contents, this may be a partial update,
 and the destination should not be removed, so `copy_dir()` should be used
 instead.

 Follow-up to [55204], [55219], [55220], [55223], [55226].

 Props afragen, costdev, swissspidy.
