Subject: [PATCH] Update _plugin_extending_campaigns.md

documentation update as i ran into a problem trying to execute the code in the previous version of this example.
Now it implements `Symfony\Component\EventDispatcher\EventSubscriberInterface` instead of extending `Mautic\CoreBundle\EventListener\CommonSubscriber` as it does not exists in mautic anymore.
