Make $handleName nullable in afterAddHandle plugin

[peterjaap]

We are running into this error, which is fixed by adding null to the type hint.

TypeError: Vendic\OptimizeCacheSize\Plugin\RemoveHandlersPlugin::afterAddHandle(): Argument #3 ($handleName) must be of type array|string, null given, called in /data/web/releases/20250401082050/vendor/magento/framework/Interception/Interceptor.php on line 146 and defined in /data/web/releases/20250401082050/vendor/vendic/module-optimize-cache-size/Plugin/RemoveHandlersPlugin.php:24
