Enhance Connect method documentation and signature

Updated the `Connect` method in the `RTSPClient` class to improve XML documentation, including a new user certificate selection callback parameter. Changed the method to accept a `Uri` object instead of a string URL and updated the logging statement accordingly. The method now calls an overloaded version that takes the `Uri` directly, while RTP transport initialization remains unchanged.
