Retrieves path of post type archive template in current or parent template.

The template hierarchy and template path are filterable via the {@see ‘$type_template_hierarchy’}
and {@see ‘$type_template’} dynamic hooks, where `$type` is ‘archive’.

function get_post_type_archive_template() {
	$post_type = get_query_var( 'post_type' );
	if ( is_array( $post_type ) ) {
		$post_type = reset( $post_type );
	}

	$obj = get_post_type_object( $post_type );
	if ( ! ( $obj instanceof WP_Post_Type ) || ! $obj->has_archive ) {
		return '';
	}

	return get_archive_template();
