[docs] [issue37891] Exceptions tutorial page does not mention raise from

New submission from Niels Albers <nralbers at gmail.com>:

raise <Exception> from <exception instance> has been in the language since python 3, yet the tutorial page teaching about exceptions does not mention it. (see https://docs.python.org/3.7/tutorial/errors.html#raising-exceptions)
It would be especially helpful to language newcomers to touch on the possibility of passing error context when raising a new exception in an exception handler.
