Integrate pretty_yaml for the YAML formatter (#130)

* `dprint config add g-plane/pretty_yaml`

* Prefer single quote for YAML strings to keep current style

I should remember they recommend to use double quoting
https://github.com/g-plane/pretty_yaml/blob/444cc16883442534fcbf61437582fe4d63d22bb6/docs/config.md#L41

* `dprint config update --yes`

* Uninstall yamlfmt since using pretty_yaml

* `dprint fmt`
