build(sdk): remove dependency on six by modifying vendored libs

[dmitryduev]

Fixes WB-NNNN
Fixes #NNNN

Description

This PR removes dependency on six by modifying vendored libs gql and graphql-core.

Concretely what I did was:

• Downloaded the vendored versions of the libraries from PyPI (tar balls)
• Initialized git in the uncompressed directories, applied our wandb-vendor diff's (manually)
• Identified all files that used six with git grep " six" (to catch import six and from six import ...)
• Ran pyupgrade --py36-plus <filename> on each identified file and manually made sure the result was good.
• Generated new diffs with git diff > wandb-vendor.diff, ensured they looked good
• Copied stuff over to the SDK and checked the diffs once again.

Testing

CI!

I think updating the wandb-vendor.md files (3 of them) with the procedure mentioned in the PR (or one line summary of it so people can find the change from the PR), and optionally a separate diff for the pyupgrade stuff (rather than merging them into one diff) makes sense to me.
The diff is bonus... the main thing we want to know is the steps done on the base vendored code so we can reproduce them if needed.. technically the diff can be found in git so if it isnt totally necessary.
also need to resolve the conflict from the watchdog prefix vendor that just went in.

@raubitsj cleaned this up and addressed your comment (mainly, rm'ed all the non-six-relevant pyupgrade stuff).
