Scripts: Fix a PHP error in admin-ajax calls.

When making an ajax request, `wp_enqueue_registered_block_scripts_and_styles()` checked if `is_admin()` was true before accessing `$current_screen`, rather than checking if `$current_screen` was defined. This is usually fine, execept for in ajax requests.

See #45203.
