Comment:

 In [changeset:"41885"]:
 {{{
 #!CommitTicketReference repository="" revision="41885"
 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.
