Similar to #33701's suggestion to extend the debug page.

Python 3.11 adds `BaseException.__notes__` which may include extra
information about the exception. These are expected to be used by certain
libraries that can attach context to exceptions.

enriched-with-notes-pep-678

The default Python error handler displays these. Django's debug page
should too, to aid debugging.
