Update Ray tutorial to use Ray job submission method

[hongbo-miao]

Is your feature request related to a problem?

Currently Ray tutorials are using Ray client endpoint:

• https://www.getdaft.io/projects/docs/en/stable/distributed/?h=dashboard
• https://www.getdaft.io/projects/docs/en/stable/integrations/ray/

Ray client (10001) is not recommended way based on the message from Ray team: ray-project/kuberay#1645 (comment)

It would be great to update the Ray tutorial, thanks! ☺️

Hmm interesting. I wasn't aware that they discouraged use of Ray client.

We have noticed performance issues when using Ray client vs running in a job, but for the most part we do encourage use of Daft from a Ray job.

Thanks for bringing this up. We will chat with Ray folks!
