Upgrade black for new remote-dev boxes

Description

We are seeing this with new remote-dev boxes:

Traceback (most recent call last):
  File "/home/ubuntu/.cache/pre-commit/repoc0u0pk8f/py_env-python3/bin/black", line 8, in <module>
    sys.exit(patched_main())

Tests

rm ~/.cache/pre-commit
git commit README.md

How will this change be monitored? Are there sufficient logs?

@csjiang in order for this PR to pass, we need to rebuild remote-dev with the newest version of black.

New remote-dev boxes won't be able to run pre-commit hooks until this PR is in.

If other dev environments do not auto-upgrade black, then they need to run:

rm ~/.cache/pre-commit

@joaquincasares gotcha on the remote dev stuff but i think to get PR to pass CI checks is just fixing the spacing w the operator on those two extra files right?

i'll rebake remote dev after this goes into master to get ahead of the pre-commit stuff, but can we fix those two files so this PR can be merged?

Sounds good!

I'll ping you when this is merged and then open up a second PR.

Thanks!
