Combining WithRelayNetwork() and WithDirectNetwork() throws a bare System.Exception exposing the internal type name NetworkInfoOption

Steps to reproduce:
1. Create a new project using the Universal 3D template
2. Install Services Multiplayer package via Package Manager window
3. Add the “NetworkOptionConflictRepro.cs” provided script component to a GameObject in the Hierarchy window
4. Enter Play mode
5. Observe the Console window

Actual results: "Exception: NetworkInfoOption Option is already included”: a bare System.Exception naming a type that is not part of the public API

Expected results: a SessionException with SessionError.InvalidParameter, naming the two public methods that conflict
