Ubi gateway

[akihikokuroda]

Summary

Change the base image of the gateway pod to the UBI base image.

Details and comments

I couldn't find the python 3.10 UBI base image. There are only 3.9 and 3.11 UBI images. This PR used the python 3.11 UBI image. The Ray version is also changed to 2.22.0 for python 3.11 support.

There are issues in the decorator example with the 3.10 client. The client has to be 3.11 to use the decorator.

LGTM, though since this requires bumping the Ray version I think we should hold off on merging it until after the next release as per #1272 (comment)
