In 55421:

Database: Remove the check for sitecategories table on Database Repair screen.

The table is no longer created by core as of WordPress 3.0, and support for global terms was removed in WordPress 6.1, so $wpdb->sitecategories is unset by default.

This commit resolves a "passing null to non-nullable" deprecation notice on PHP 8.1:

Deprecated: addcslashes(): Passing null to parameter #1 ($string) of type string is deprecated in wp-includes/class-wpdb.php on line 1804

The tables_to_repair filter is available for plugins to readd the table or include any additional tables to repair.

Follow-up to [14854], [14880], [54240].
