DeprecationWarning: 'importlib.abc.ResourceReader' is deprecated and slated for removal in Python 3.14

I'll approve the PR, but I wonder if it wouldn't be better to fix the root cause by importing from importlib.resources.abc.ResourceReader? I haven't looked at the code, but maybe that's difficult if make_abc_subclasses() is generic.

[iritkatriel]

The Merged PR suppresses the warning, but the test needs to be rewritten before we get to 3.14.

In #93963, I'm dealing with the deprecation (and ultimate removal). My recommendation there is to simply remove these tests. I'm closing this one in favor of #93963.
