Compatibility with Jupyter Server 2?

[JasonWeill]

Has anyone tested jupyter-server-proxy with Jupyter Server version 2? This version is coming out soon, and users will expect to use the server proxy with it.

Thanks for opening this issue @jweill-aws

I am seeing a problem when using JSP with Jupyter Server 2, but I believe it is a bug in Jupyter Server 2. Details can be found here: jupyter-server/jupyter_server#1012

This is the current test matrix

jupyter-server-proxy/.github/workflows/test.yaml

Lines 39 to 41 in a82f70a

	jupyterlab_version: [2, 3]
	python: [3.6, 3.7, 3.8, 3.9]
	jupyter_app: [notebook, lab]

I think changing jupyter_app to something like [notebook, jupyterserver1-lab, jupyterserver2-lab] could be worthwhile?

I think it would be helpful to explicitly test JS 2 combinations. I do have at least anecdotal evidence now that JSP work with JS2.

Seems like there is an issue with the jupyterlab extension tests, but only that.
