[Python 3.9 compat] type is now subscriptable.

[JulienPalard]

Since Python 3.9, type is made subscriptable by Objects/abstract.c (python/cpython@48b069a), to allow, for example, type[int].

print(type[int])

which give:

test.py:10:6: E1136: Value 'type' is unsubscriptable (unsubscriptable-object)

while the code works.

Related to #3890.
See also #3882.

@JulienPalard thanks for the report.

This seems to be fixed with: pylint-dev/astroid#885
So non blocker after an astroid update 🎉
