Change game port from 7777 to 8777

The official Astroneer site calls out that dedicated servers need to run on Port 8777, more information can be found here https://blog.astroneer.space/p/astroneer-dedicated-server-details/

I was not able to get the server running myself until I made this correction myself on my own AMP game server. This will help majorly with a ton of people running into these issues as stated in the Astroneer Discord server.
