Feature: Allow setting a different port in the motd (#4293)
* Allow changing the broadcasted port using a system property. This may be needed if the port Geyser runs on & the port Bedrock players connect on do not match - e.g. due to port forwarding/different routing. * initial stab at making the broadcast port an (unsafe) config option * Automatically set broadcast port to be the bind port unless manually overridden * Warn about broadcast port mismatch * Use 0 instead of -1 as indicator to broadcast the port geyser is running on
