[Feature] Export the IsTerminalServer property #1665

Summary of the new feature / enhancement

The OperatingSystemInfo has more properties as are exported by the Toolkit.
Currently I have a use case for IsTerminalServer. I would be glad if those would be exported as well.

I am aware of Get-ADTOperatingSystemInfo but the properties would change during the deployment and therefor it would be unnecessary to call it multiple times.

Proposed technical implementation details (optional)

Export the rest of the properties from OperatingSystemInfo
