* Fix New Notebook issues
- Fix#5338 New Notebook menu item should be next to New Query
- Fix#4936 Add a shortcut to create a notebook in the document well
Created a built-in New Notebook command
that routes to the existing extension-based command.
This avoided a rearchitecture that was more complex that seemed worth it.
Per VSCode patterns, used a _ modifier for the existing command so it's "private"
- Azure token wasn't being copied into profile so expand didn't work, it spun forever
- Fixed this by saving in password/token after the connection profile copy, & refactored to be cleaner
- We should ideally ensure session notifies resolves even on fail so if there's a different error it'll break, not spin forever. Punting this part of the fix for now
- Also doesn't solve issue where we always try to connect even if user + password combo isn't saved. Will investigate / work in a separate PR on this.
