Role/Capability: Prevent a fatal error when checking a language capability early or in the frontend. 

The meta capabilities `install_languages` and `update_languages` rely on the admin function `wp_can_install_language_pack()`. That function in turn relies on `request_filesystem_credentials()`, so it needs to be ensured that this function is available as well.

Fixes #42230.
