Remove Interrupt buttons and commands from Jupyter

[roblourens]

• "Run all" on a long notebook eg Titanic.ipynb
• The interrupt button blinks on and off
• This is actually contributed by Jupyter, and it looks like the when clause changed recently @joyceerhl

Filing this because @kieferrm mentioned it, we could leave the when clause alone (if that is causing the issue), but next month we have this button in vscode itself. See microsoft/vscode#133776 also

Even if we fixed this, i don't see a point, as we're planning on moving this into core in the same iteration!
To be discussed whether we want to fix this in Jupyter or not.

Suggestion

• VS Code enables the icon only when cells are queued/running
• Remove interrupt from Jupyter
  • Currently the interrupt only appears in global toolbar & not in editor toolbar (moving to core will fix this - hopefully)
