Feature: Allow disabling vim for certain contexts, e.g. Jupyter notebooks

[corneliusroemer]

Is your feature request related to a problem? Please describe.
VSCodeVim is known to make Jupyter notebooks hard to use. This issue has received lots of comments and thumbs even after it was closed, showing that this continues to be a real problem for many users: #6950

Describe the solution you'd like
The vim extension should offer a better way to coexist with Jupyter notebooks without requiring users to manually switch off the extension. For example, it would be great if one could configure vim to be disabled in jupyter notebook text fields.

Additional context

• Issue Disable vim *only* for jupyter notebook editors  #6950 was closed as a duplicate/completed, but it doesn't really seem to be either.

  • jk on cell boundary (it should move to near cell) [marked as fixed]
  • alt+delete to clear output doesn't work
