Migrate to new FCM API v1 from GCM

[yjinchoi]

Hello, everybody.

I'm really new to Rocket.Chat and I'm trying to white labeling and
trying to my own firebase project for mobile app push notification.
I had a problem push notification not sent to firebase.
I found a problem firebase project let old GCM API as disabled.
I can fix a problem at thist time enabling old GCM API.
But google saying I must migrate GCM API to FCM API v1 until 06/20/2024.

Is there any plan for migrating GCM to FCM API v1 for Rocket.Chat?
