[issue41576] document BaseException in favour of bare except in error tutorial

[Thomas Grainger]

Thomas Grainger <tagrain at gmail.com> added the comment:

The purpose of this tutorial section is to document how to catch all types of exceptions and extract the type and value. When this is required, `BaseException as err:` is the preferred approach.

This document still mentions the alternative approach so that readers will know what it means when they encounter it, and know to upgrade it to the py2.4+ syntax
