Tested these changes through the SDK demo notebooks using quay.io/mcampbel/ray:220-py39-cu118-dev as the ray image.

• Was able to run basic ray demo.
• Was able to run job client demo and use gpus.
• While running basic_interactive demo I see this info message (see screenshot below). I wasn't able to run through the entire demo due to issues with training script which I am currently looking into. But was able to run ray.init successfully.
• Was able to run local interactive demo - including ray.init but also seeing the info about the python version mismatch
  

This is not an error as such and I was able to submit jobs successfully.

The e2e tests fail here due to the CertGenerator image on the CFO side when setting up the Kind Cluster.
Here is proof of a passing e2e test with the new Ray image for the CertGenerator.

I have made a PR to update the CFO with the new image
