Adds preview features for black formatter (#192)

# Description

Adds `--preview` feature to the black formatter which also takes care of
the string representations in the code. This feature will become the
default setting in the next release of black
(https://github.com/psf/black/issues/1802).

## Type of change

- New feature (non-breaking change which adds functionality)
- This change requires a documentation update

## Checklist

- [x] I have run the [`pre-commit` checks](https://pre-commit.com/) with
`./orbit.sh --format`
- [ ] I have made corresponding changes to the documentation
- [x] My changes generate no new warnings
- [ ] I have added tests that prove my fix is effective or that my
feature works
- [ ] I have updated the changelog and the corresponding version in the
extension's `config/extension.toml` file
