📝 Make "setuptools entrypoint" term generic

This feature grew out of `setuptools` but the modern interface for
extracting this information from the distribution package metadata
is `importlib.metadata`. So the patch attempts to reflect this in
the documentation messaging.

Refs:
* https://docs.python.org/3/library/importlib.metadata.html#entry-points
* https://packaging.python.org/en/latest/guides/creating-and-discovering-plugins/#using-package-metadata
