Add American Truck Simulator (#332)

* Add American Truck Simulator

The game requires additional setup which are linked in the ExtraSetupStepsURI. Linux only or Docker on Windows as there are issues running as NETWORK SERVICE in Windows.

After this is fully reviewed, I'll convert it to work for Euro Truck Simulator 2 as well.

* Update american-truck-simulator.kvp

* Requested changes + moderators

* Update american-truck-simulatorupdates.json
