[issue45449] Document that collections.abc types are subscriptable

[Filipe Laíns]

Filipe Laíns  added the comment:

Just to clarify: some type checkers will still allow using them as type hints 
in Python versions before 3.9, but `from __future__ import annotations` needs 
to be used so that we don't error out at ruuntime.

[issue45449] Document that collections.abc types are subscriptable

[Filipe Laíns]

New submission from Filipe Laíns :

Since 3.9, the types in collections.abc are subscriptable and can be used as 
type hints, but this is not documented.
We should write something similar to what's on the typing module documentation 
for the deprecated types.
