[#8386] did some crazy hacks to remove our dep on chardet
(LGPL licensed which is no good). Further discussion at https://issues.apache.org/jira/browse/LEGAL-572
We can upgrade and undo that because requests 2.26.0 changed its dependency. https://docs.python-requests.org/en/latest/community/updates/ says:
Instead of chardet, use the MIT-licensed charset_normalizer for Python3 to remove license ambiguity for projects bundling requests.
Other upgrades would be good too
