Resolve ambiguity with apprise.plugins module namespace

While the namespace is physically made of modules, it has been amended
to be the namespace home for the corresponding notifier classes as well.

This turned out to confuse both humans and machines on various ends.

While it has apparently worked for a while, it croaks on Python 3.11
now, and is not considered to have been a good idea in general.
