Not compatible with Framework-Bundle 5.0

[alcohol]

Framework-Bundle requires Event-Dispatcher, see changelog for v5:

https://github.com/symfony/event-dispatcher/blob/master/CHANGELOG.md#500

The following change breaks code in this bundle:

• The Event class has been removed in favor of Symfony\Contracts\EventDispatcher\Event.

The Event class was already deprecated since 4.3 btw. So I'm not sure why nobody reported this before :-(

Part where it goes wrong: https://github.com/nelmio/NelmioSecurityBundle/blob/master/ContentSecurityPolicy/Violation/Event.php#L14
