Was broken after python3.8 upgraded to 3.8.6 due to this change:
bpo-41314: Changed the release when from future import annotations becomes the default from 4.0 to 3.10 (following a change in PEP 563).
The build is currently broken on master and 20.03. This upgrades to the latest
version and also disables the bad py2 test. I spent a long time trying to figure
out what the issue is, but since it's disabled upstream on python3 anyways let's
just skip it on python2 as well.
ZHF: #80379
