Open notebook with editor or JSON doesn't work

[davidbrochart]

Description

In the file browser, right-clicking on a Jupyter notebook and selecting "Open With -> Editor" or "Open With -> JSON" opens the notebook, as if "Open With -> Notebook" was chosen.

Reproduce

1. Right click on a notebook file.
2. Choose "Open With -> Editor" or "Open With -> JSON".
3. See that a notebook document is opened (and a kernel launched), not the file editor or the JSON representation.

Expected behavior

The file editor or JSON representation should be opened.

Context

• Operating System and version: Linux Ubuntu 21.04
• Browser and version: Firefox 94.0
• RetroLab version: 0.3.13

Thanks all. Closing in favor of #290 so we can keep the conversation in one place.

This should now be possible with notebook>=7.0.0a2 (implemented in jupyter/notebook#6315):
