Hiding Methods Cannot Be Mocked

[JasonBock]

To reproduce:

"""
using Rocks;

#nullable enable

namespace MockTests
{
	public class Credentials { }

	public class NewCredentials : Credentials { }
			
	public class BaseCopy
	{
		public virtual Credentials Copy() => default;
	}

	public class NewCopy : BaseCopy
	{
		public new NewCredentials Copy() => default;
	}

	public static class Test
	{
		public static void Generate()
		{
			var rock = Rock.Create<NewCopy>();
		}
	}
}
""";

This gives the following error:

error CS0506: 'CreateExpectationsOfNewCopyExtensions.RockNewCopy.Copy()': cannot override inherited member 'NewCopy.Copy()' because it is not marked virtual, abstract, or override

I don't know if the inheritance relationship with the return value types matters, but, Rocks needs to detect that Copy() can't be mocked.
