TypeError: Plain typing.NoReturn is not valid as type argument in Astroid 2.8.5 + Python 3.7.0/1

[drasmuss]

Steps to reproduce

1. Use Python 3.7.0 or 3.7.1
2. pip install astroid==2.8.5
3. python -c "import astroid"

Current behavior

An error is raised

TypeError: Plain typing.NoReturn is not valid as type argument

In this commit b62f243#diff-039e09546480e9ce70fc9a23e975f1ac2364f6d0192e330311d204653947a216R34 there is a conditional import that checks if Python >= 3.6.2, but that should also include Python 3.7.0 and 3.7.1 (which have the same issue as Python 3.6.0/1).

Expected behavior

There should be no error

python -c "from astroid import pkginfo; print(pkginfo.version)" output

This raises the same error as above

This seems to be caused by https://bugs.python.org/issue34921

Perhaps we also need to update the import guards in pylint?

I was in the process of adding flake8-typing-import to the pre-commit hooks but it seems it's not yet detected.
