jupyterlab related: better error message if missing jupyterlab-manager?

See original GitHub issue

Hi,

I am not sure if I should open this in here or in jupyterlab repo. Basically I got bellow error in console

Error: Object 'jupyter.widget' not found in registry

After googling for a while without hope, I realized that I need

jupyter labextension install @jupyter-widgets/jupyterlab-manager

Better error message would be super helpful.

@hainm - it looks like this might take some changes in comm messages, or at least in the comm implementation (if this close reason uses metadata), so bumping to the Future milestone.

I suppose it should be something enum-like that’s stable and has an official meaning, so kernels/frontends can rely on it. I happen to like strings for this kind of thing a little better than integers. Perhaps reason for the strict, stable enum value (e.g. ‘notarget’) and message for a human-readable info that can vary?
