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].
