VSCode Tweaks (#914)

# Pull Request

## Title

Revert back to black VSCode extension.

---

## Description

The pre-commit extension has issues in DevContainer environments where
pre-commit is not installed on the host.

This PR reverts to the VSCode black formatting extension for interactive
formatting and adds some additional attempts to make the isort
equivalent that'd we'd otherwise get out of pre-commit to happen as
well.

Note that these will be best effort for now. pre-commit formatting rules
will still be authoritative.

---

## Type of Change

- 🛠️ Bug fix

---

## Testing

Local edits.

---

## Additional Notes (optional)

No guarantee that this is perfect unfortunately.
