chore: Bump black version

[nj1973]

Description of changes

The pinned version of black we use for formatting does not match the Black extension in VS Code which results in unnecessary manual executions of black to format using an older spec.

As we only test on Python 3.10+ I've picked the latest version of black which drops 3.9 support. We can cycle back if we think development on 3.9 is a requirement.

Issues to be closed

Closes #1693
