datafusion-ray is not published to pypi.org

Hi

We are trying to use datafusion-ray. To get started we tried to pip install datafusion-ray. However `datafusion-ray` is not published.

I tried installing directly from github like this :
```sh
poetry add git+https://github.com/apache/datafusion-ray.git

- Installing datafusion-ray (0.1.0 2783613): Failed
```
Failure reason is not displayed even in `--verbose` mode.
If someone wants to do datafusion + ray, should we continue using raysql till then ?

I would like to contribute here if you are open for it.
