[Menu] Shells sub-grouping

[nunix]

Description of the new feature/enhancement

for some (crazy) fans of having several shells, the selection menu can become very long very fast (see picture below).

It might be nice to have a "sub-grouping" for the different shells, so the menu would remain more clean.
At first, it could even be the "discovered shells" that could all be in a sub-group, so we could customize them and bring them back to the main menu

Proposed technical implementation details (optional)

The nearest solution that already exists, might be the browser favorites, with only 1 level deep to keep it simple.

@DHowett-MSFT this doesn't only apply to multiple WSL distributions. It could be that we only have one WSL distribution but have a number of SSH connections to remote servers. Right now, using solutions like cmder, we have something like this:

So yeah, it would definitely be great. I am liking Windows Terminal so far.
