Horizontal separators in Python interpreter list

[cdce8p]

microsoft/vscode#137745

With the last release, the Jupyter extensions added horizontal separators with labels to the notebook kernel list. The Python interpreter list is already sorted. If it's possible, I think it would be a nice usability improvement to add separators there as well.

@karrtikr I just built the extension from the main branch to have a look for myself. It's just like I had imagined it, a great addition! Thanks for implementing it! Looking forward to using it in production 😍
