Removed pleroma.notifications.enable_follow_request_notifications config switch (follow request notifications are now enabled by default and could not be switched off).
Note: requires PleromaFE bundle: !2462 (merged) (or newer)
Note: that would break compatibility with older PleromaFE versions. Assuming the case of running latest BE with older FE an edge case. Still, for such an edge case we might instead keep pleroma.notifications.enable_follow_request_notifications config switch but make it true by default. Thoughts?
