This adds basic compatibility for JupyterLab-v3.6.
It doesn't add the expression renderer, and I am not sure we should even try. But it does actually render myst again, which is probably good that it isn't a fully broken experience.
@agoose77 I think that we can merge this in, we should suggest the 1.x series for folks with JupyterLab 3.6 installed, but this at least makes the extension mostly work.
