Message:

Abilities: Return the site locale for the core/get-site-info language field

The core/get-site-info ability resolved the language field via get_bloginfo( 'language' ), which runs through determine_locale() and can return the current user's locale in the admin context. As a site-level ability, the language field should consistently represent the site locale. Use get_locale() (with _ normalized to -) instead so the value reflects the site locale regardless of the requesting user.

Props iamadisingh, afercia, audrasjb, yusufmudagal, r1k0, gziolo.
Fixes #64977.
