Symfony version(s) affected

>=5.3.0

Description

The Gitter API is no longer available, and was slated for removal as far back as January 2023 (https://blog.gitter.im/2023/01/16/gitter-is-going-fully-native-matrix-in-feb-2023/), with removal taking place in February 2023 (https://blog.gitter.im/2023/02/13/gitter-has-fully-migrated-to-matrix/).

What can be done

Since this API is no longer supported, Symfony should:

1. remove the currently provided (and unusable) Gitter Notifier Component

(and optionally)

2. create a generalized Matrix Notifier Component so users of Gitter (and any other Matrix chat server) can use The Notifier component from Symfony to send messages to the users.

How to reproduce

Attempt to use the Gitter Notifier component.
