Since http://api.wordpress.org/patterns API supports array parameters, there is no need to implode slug values inside the _register_remote_theme_patterns function. Both WP_REST_Pattern_Directory_Controller and _register_remote_theme_patternsmust be updated to support array request arguments. Props antonvlasenko. Fixes #55574. Follow-up #55505, [53152].
