Is your feature request related to a problem?

seems like hot chocolate mongoDB provider does not include dictionary type/ operation handlers. they are not serialized properly and the projection / filtering queries are based on the wrong serialization

The solution you'd like

• the dictionary responses should be serialized like the default json serialization of dictionaries.
  I am not sure about the proper implementation but i think it might need FilterInputType, OperationHandlers,...

• I am willing to open a PR on this but i will need more guidance for the implementation.
