Pull Requests.

:ghpull:`13162`
- fix compatibility with PyQt6, PySide 6 :ghpull:`13172`. This may be of
  interest if you are running on Apple Silicon as only qt6.2+ is natively
  compatible.
- fix matplotlib qtagg eventloop :ghpull:`13179`
- Multiple docs fixes, typos, ... etc.
- Debugger will now exit by default on SigInt :ghpull:`13218`, this will be
  useful in notebook/lab if you forgot to exit the debugger. "Interrupt \ 
Kernel"
  will now exist the debugger.
