[BUG] wmcserver not able to get query port from config

[xenorio]

User Story

WaterfallMC servers are unable to read the query port from config, using "NOT SET" as the port instead

Basic info

• Distro: [Arch]
• Game: [WaterfallMC]
• Command: [Monitor, Details]
• LinuxGSM version: [v21.5.1]

Further Information

This is caused by a "typo" in info_game.sh I've already got a PR in the works

To Reproduce

Steps to reproduce the behaviour:

1. Set a query port
2. Run details command
3. Query port is "NOT SET"

Expected behaviour

The query port should be set to what it is in the server config
