PHP Deprecation Notice

I just activated DocketCache on a new site with PHP 8.4 and got following deprecation notice:
PHP Deprecated: Nawawi\Symfony\Component\VarExporter\VarExporter::export(): Implicitly marking parameter $isStaticValue as nullable is deprecated, the explicit nullable type must be used instead in /var/www/some_website/wp-content/plugins/docket-cache/includes/vendor/symfony/var-exporter/VarExporter.php on line 41

Besides that minor thing, the plugin works as expected and i like that you use parts from Symphony.
Keep up the good work.
