Media: Edit new hook name in `get_available_post_mime_types()`.

This is a follow-up to [56452] in which a new filter hook was added to `get_available_post_mime_types()` to override a potentially slow query. This renames the previous hook from `get_available_post_mime_types` to `pre_get_available_post_mime_types` for clarity.

Props rcorrales, emrikol, johnbillion, joemcgill, mukesh27.
Fixes #52759.
