ipykernel.comm.Comm is deprecated

And therefore tests of nbclient fail with the latest ipykernel with:

E             Full diff:

I just ran this test with the latest ipykernel, and it passes successfully. Actually, the Other Comms.ipynb notebook is doing the right thing by using the comm module. What version of nbclient are you testing?

[frenzymadness]

You are right, I'm sorry for the noise. I was testing an older version of nbclient with the latest ipykernel.

No worries, thanks for your work on packaging!
