`traceback.format_exception(...)` usage that is compatible with Python 3.7 and 3.11 (#15599)
* Usage that is compatible with Python 3.8 and 3.11

> Since Python 3.10, instead of passing value and tb, an exception object can
  be passed as the first argument. If value and tb are provided, the first
  argument is ignored in order to provide backwards compatibility.
