[issue45776] abc submodule not an attribute of collections on Python 3.10.0 on Windows

> this coincides with collection ABCs being made unavailable directly from `collections` with this 3.9 -> 3.10 version change

Direct access from collections was removed after being deprecated for almost almost a decade ago:
 
    "Using or importing the ABCs from 'collections' instead "
    "of from 'collections.abc' is deprecated since Python 3.3, "
    "and in 3.10 it will stop working"

So Windows is correctly reporting an AttributeError.

The mystery is why it is still accessible on a Mac.  That seems like a bug.
