pre-commit tool setup issue (pip)

[c-taylor]

I encountered a few issues when setting up the tools for pre-commit hooks on a recent brew:

• 'Modern' brew python does not have 'pip' only 'pip3'
• virtualenv and other yapf tools scripts hard require pip
• Scripts use python3 by name, but not pip3 (seems inconsistent)
• repo yapf is from 2021

Additionally: pip installs make me uncomfortable. Maybe consider using system yapf/clang-format and publishing config rather than version locking?

Reproduction: Remove all of your yapf/clang tooling in your repo Try to recreate it
