Jupyter breaks in older DAD compute environments when adding domino-code-assist library

Version/Environment (if relevant):

This applies to any Domino version when using older "Domino Analytics Distributions" environments that were released prior to Domino version 5.0.

Issue:

When adding domino-code-assist to requirements.txt, if you are using Jupyter with an old "Domino Analytics Distributions" compute environment, like the Ubuntu18_DAD_Py3.8_R4.0-20210709_noCUDA from Domino 4.5, the Workspace IDE will fail with an error in the User log No module named 'jupyter_server.contents'like:

2023-09-14T17:51:14.204Z: ModuleNotFoundError: No module named 'jupyter_server.contents'

 Other IDEs like VScode, R and JupyterLab are not impacted by this.

Root Cause:

There is a problem in the underlying libraries.  It is due to nuances or defects in the chain of dependencies across the many version changes of various libraries since 2021.

Resolution:

To resolve the problem add a new library to your project's requirements.txt.  Add  traitlets<5.10.0 above (prior to) domino-code-assist then save and launch an entirely new workspace (rather than restart).
