[issue37284] Not obvious that new required attrs of sys.implementation must have a PEP.

[Eric Snow]

New submission from Eric Snow <ericsnowcurrently at gmail.com>:

PEP 421 added sys.implementation for Python implementors to provide values required by stdlib code (e.g. importlib).  That PEP indicates that any new required attributes must go through the PEP process. [1]  That requirement isn't obvious.

To fix that we should add a brief note to the sys.implementation docs [2] identifying the requirement.
