Renames Interface menu to "Open in", shortens menu options

[JasonWeill]

Fix for #6806.

Renames the "Interface" menu to "Open in" and renames the commands to just the name of the desired interface.

In Notebook view:

In Lab view:

Note that the commands have particularly short names because Lumino doesn't yet allow custom menu item labels; see jupyterlab/lumino#570 .

Thanks @JasonWeill for looking into this.

Would it be possible to keep the longer form when the command is displayed in the command palette? With this change on Binder it doesn't seem possible to open with another interface via the command palette anymore:

But it shows entry with JupyterLab only:

Just as a hopefully helpful note: this can be implemented by using functional label testing for args['isPalette'] instead of hard-coded label. For example, see the terminal terminal:create-new command.

@krassowski I just pushed a change that adds a separate "short label" for use in the menu, making the longer "label" used in the command palette instead. When I built my changes locally, though, I still see the short label in both places. Can you please take a look?

@krassowski Attempting to implement approach described by you in notebook PR #6847, in this commit but I'm missing a lot of details and could really use a consultation if/when you would have some time. Do I need to have a separate addCommands function for this to work?

Edit: alternative approach where I register 2 commands with different labels but same functionality and assign one to the menu and one to the command palette seems to work (see #6847 Changed Files)

Closing as fixed by #6847, thanks!
