GH-92584: Remove distutils mentions from importlib.metadata docs

[AA-Turner]

eps.groups returns a set, so I've also changed the return type.

Thanks for the contrib, but I'm reluctant to accept this change for a few reasons.

First, these docs changes originate in the importlib_metadata project, so probably should be contributed there first. They get synced into CPython as a matter of course, but contributing here first leads to conflicts and is more difficult to backport.

Second, the distutils.commands entry point is just as viable as console_scripts. Both are still actively supported by Setuptools, even while distutils is removed from the stdlib. There are no plans currently to even deprecate distutils.commands, so the value here is small.

Given my concerns with the changes, I propose instead to open an issue with importlib_metadata describing the motivation for making changes and then propose a change there.

Thanks.
