Expo makes implementing push notifications almost too easy. All the hassle with native device information and communicating with APNs (Apple Push Notification service) or FCM (Firebase Cloud Messaging) is taken care of behind the scenes, so that you can treat iOS and Android notifications the same, saving you time on the front-end, and back-end!

this PR will add the support of [Expo Notification](https://docs.expo.dev/push-notifications/overview/) as a bridge to Symfony

✏️  this is a work in progress I would love to hear your feedbacks to improve it.
