prodigy docs: jupyterlab-prodigy extension missing version

just found: the docs start with a hint to the jupyterlab-prodigy extension. That`s fine, but one line more let it work:

pip install jupyterlab==1.0.0rc0

this will direct to the right version.
This is important because the jupyterlab extension repo doesn't list the prodigy extension and the current version of jupyterlab doesn't work because of the setup requirements.

Ah, good point! We currently list this on the repo, but not in the docs. We should probably also update the requirements and relax them a little – I'll look into that :+1:
