feat: Add python3.10 support (ugly workaround)

[bertonha]

the sub dependency of apns2 hyper is completely abandoned and it does not support python 3.10
simple because it uses some packages from collections where on python 3.10 it moved to collections.abc

I think the clean way to properly fix it, would be to move to a more maintained package to do Apple Push Notifications.
which might be aioapns

apns2 is a pain since no one maintains this valuable package. We should get everyone to use a fork instead. aioapns is for asyncio.

We can name the fork apns2-py and set it up in Jazzband for maintenance.
