Description (last modified by Adam Johnson)

Similar to these tickets for extending the debug page for Python 3.11 exception changes: #33747, #33752.

Python 3.11 adds "where in the line" highlighting to tracebacks:

$ python3.11 t.py
Traceback (most recent call last):
  File "/.../example.py", line 5, in <module>
    formula(1, 0)
    ^^^^^^^^^^^^^
  File "/.../example.py", line 2, in formula
    return a / b + b / a
           ~~^~~
ZeroDivisionError: division by zero

Release note: https://docs.python.org/3.11/whatsnew/3.11.html#enhanced-error-locations-in-tracebacks

It would be good if we could use this on Django's error pages as well.

The new code column information API may be required: https://docs.python.org/3.11/whatsnew/3.11.html#column-information-for-code-objects . Note it can be disabled.
