Subject: [PATCH] fix uncaught `BdbQuit` exceptions on ipdb `exit`

- `BdbQuit` is now handled in the top-most scope of `InteractiveShell.run_code`. This ensures that `BdbQuit` is correctly handled but can still do its job of breaking out of all user code/loops/further breakpoint requests. Hopefully will work better than previous attempts, which put the `BdqQuit` handling in `Pdb.set_trace`

- fixes:
  - jupyterlab/jupyterlab#12501
