[docs] [issue34538] Remove encouragement to author a base class for all Exception subclasses in a module

Brett Cannon brett@python.org added the comment:

I think the question is how often in real code to people want to catch all exceptions produced by a package or module but not any others. Perhaps it would be better to re-word the advice that when there are many related exceptions that it is suggested you have a base class for them?
