Query port is game port + 1. Can use the Source protocol.

Would be nice to have some kind of "default" game type in case it is not supported yet, we could still try to use it rather than get fat exception. If I find time I will try to create PR for this. I used "valheim" type temporarily to show the status of the enshrouded server, so it definitely works as a work around.
