Travis Ralston 42ae5c966a Clarify the limits of prev_events and auth_events 
Fixes https://github.com/matrix-org/matrix-doc/issues/2307

These restrictions are due to a Synapse change which never made it to the spec prior to the MSC process. This is therefore documenting an omission.

Synapse's numbers are verified here: 207b1737ee/synapse/handlers/federation.py (L1183-L1213)

... and Synapse's handling of the backfill endpoint is described here: 207b1737ee/synapse/handlers/federation.py (L829-L837)

This also includes a mention that https://github.com/matrix-org/matrix-doc/pull/1594 should render the `auth_events` limitation unnecessary. 

No changes are required to the the "checks on receipt of a PDU" section of the server-server spec as it starts with "must be a valid event", to which an event is invalid if it contains too many prev or auth events.
