Display Exception notes

[jbvsmo]

Similar to my other issue #287

Python3.11 added the concept of notes on exceptions that are displayed after the exception value, in new lines (one per message).

>>> ex = TypeError(10)
>>> ex.add_note('foo is bar')
>>> raise ex
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 10
foo is bar

Latest console does not show notes yet. Ref PEP 678
