Change in EventDispatcher::dispatch parameters not reflected

Based on https://github.com/symfony/symfony/pull/28920 parameter calls should be reversed in documentation.

Furthermore, in 4.3, EventDispatcher lost its dispatch method $eventName parameter - it is commented out in the source https://github.com/symfony/symfony/blob/4.3/src/Symfony/Component/EventDispatcher/EventDispatcher.php - I guess this is a bug? Should I report an issue in the main repo?
