Update examples so they hold at least one PropertyInspector entry.

Would be nice if examples included at least one entry into an action's property inspector so we could figure out the rest via elgato's docs.

Using 7.0.0 beta for SD+ support and I can't seem to figure out how to get the property inspector to show some controls.

@nguyenquyhy You seem to be using 7.0 on the FlightTracker plugin - would be a great help if you could write a tiny example in this repo on how to do the PropertyInspector stuff for the rotary encoders. 🙏

Sure, I'll submit a PR.
