Proposed change

I would like to launch a beta version of Jupyter Notebook 7 using the nbgitpuller link for testing the a11y upgrades in JN7. https://nbgitpuller.readthedocs.io/en/latest/link.html does not have an entry for launching notebook 7.

Alternative options

There is an entry for "RetroLab". Should I use that to generate links that launch Notebook 7 in hubs where the beta version of JN7 got installed?

Who would use this feature?

We are planning to test the latest stable version of JL 4.0 and JN 7.0 in a summer course if everything falls into place before June 20th. In addition, I would like to use this functionality to test a11y upgrades in Notebook 7 and share these links with instructors who are interested to check the latest updates to the notebook.

(Optional): Suggest a solution
A similar change to the nbgitpuller web extension is appreciated - https://github.com/yuvipanda/nbgitpuller-link-generator-webextension
