[feature] Outgoing federation of avatar/header descriptions (#4270)

Signed-off-by: nicole mikołajczyk <git@mkljczk.pl>

# Description

This implementation is compatible with Iceshrimp.NET, Pleroma and Chuckya, which already support federated avatar/header descriptions. I will add support for incoming descriptions federation in this or another PR (depending on when this one gets merged).
