Collapsable cells groups to Jupyter Notebooks in VSCode

[pbower]

In the insider's build we can collapse Jupyter cells which is awesome.

Now, it would be even better if we can group cells and collapsed cells and collapse the group, with a user-entered Group name displayed.

This would mean that we turn something that was previously say '20 cells', and taking up heaps of screen real estate, into a neatly organised group. In effect, a draft for a Python module or something of that nature.

Absolute heaven.

That would be an ask on the https://github.com/microsoft/vscode-jupyter repository, not here (which doesn't have Discussions turned on, so I can't transfer this request).
