39677	Introduce capabilities for managing translations	flixos90	flixos90	"We currently have capabilities for managing core updates, plugin installation/updates and theme installation/updates. However we lack capabilities for managing translation installation/updates, so let's add them. This is especially critical as it's currently not possible to allow a user to only install/update translations while not allowing them to install/update anything else.

I suggest introducing `install_translations` and `update_translations`. I think they should be added as primitive caps to the `administrator` role (would need to happen in WP version update function), just how the other above caps work. We would then also need to add them to `map_meta_cap()`, where it could currently go into the same group as the other caps I mentioned above. However, let's also have an eye on #38673, as the changes on that ticket might require us to handle the `map_meta_cap()` stuff differently.

About usage of these capabilities, there are several areas in core where they could be used:

* `wp-admin/options.php` line 185
* `wp-admin/options-general.php` line 147
* `wp-admin/network/settings.php` line 66 and 345
* `wp-admin/network/site-new.php` line 68 and 236
* `wp-admin/update-core.php` line 617 and 732

Regarding `wp_can_install_language_pack()`, I think the `current_user_can( 'install_translations' )` check should not go into that function as that function is also used during setup where it should be accessible to anyone."	enhancement	closed	normal	4.9	Role/Capability		normal	fixed	has-unit-tests, has-patch, granular-capabilities, commit
