C# research kernel idle infinitely

[LouisSzeto]

Right after connected to the jupyter, C# research notebook's Foundation-C#-default kernel went idle forever, and cannot be activated by running cells. Now, we can only restart with a new kernel instance and run all cells before its connection with the host to get the cells executed at the instance of connection.

Note:

1. Jupyterlab version doesn't matter, version 3.2.1 to 3.4.4 have the same issue.
2. Connection to docker container didn't end
3. The below error message will pop up if running cells after it was disconnected:

This issue seems to have started since the py38 update at QuantConnect/Lean#6558

[Martin-Molinero]

Reported bugs for jupyter lab & dotnet interactive

[Martin-Molinero]

• We could potentially make the lean CLI run the notebook with net in host mode to get around this issue

Sadly network host mode is only currently working for linux see docker/roadmap#238
