PHP 8.1 incompatibility

Hi, I’ve just started testing WP with recently released PHP 8.1 and found that your plugin causes a fatal error:

PHP Fatal error:  Uncaught Error: Call to undefined method LittleBizzy\DisableGutenberg\Core\Core::detected() in \wp-content\plugins\disable-gutenberg-1.1.0\core\core.php:50
