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. git-svn-id: https://develop.svn.wordpress.org/trunk@41885 602fd350-edb4-49c9-b593-d223f7449a82
