Support jupyter-client 7.4.4 or upcoming v8 in voila 0.5

[bnavigator]

Thanks a lot everyone for investigating! It looks like jupyter_client 7.4.2 was indeed the culprit, we will have an upper-bound for now and release 0.4.0.

Please fix the incompatibility with recent jupyter-client before releasing 0.5

Still an issue with jupyter_client 7.4.8

[bnavigator]

Somehow this is no longer a problem with 7.4.8. Some underlying dependency must have fixed it.

[martinRenou]

Thanks for posting an update! We can probably change the jupyter-client dependency pinning for 0.5.0 then

[bnavigator]

I spoke too soon. My check was not thorough enough, the failure is flaky.

In the latest run, the tests pass for Python 3.8, and then hang on 3.9:
