What was the issue:
Our go-xamarin shared xamarin builder packages, does not know the nuproj project type. This cased issue, like this:
failed to create xamarin builder, error: no project found with ID: XYZ

What we changed to make it better:
As a solution, i updated the go-xamarin package to care only about archivable project types and omit other project types.
