[Docker][CI] Add Python 3.13 Ray Image to CI

[broden-wanner]

Description

Ray has supported Python 3.13 since version 2.43.0:

ray/python/setup.py

Line 30 in 744eaa9

SUPPORTED_PYTHONS = [(3, 9), (3, 10), (3, 11), (3, 12), (3, 13)]

And it would be nice to have an image built with Python 3.13 for easy use with custom Docker images.

Use case

It would be ideal to have a Python 3.13 Docker image published with Ray installed for easy creation of custom Docker images and usage with KubeRay. For instance, a rayproject/ray:2.47.0-py313 image. Initial PR is up here: #53894. I'm not super familiar with the build pipeline though and would love some eyes to see if there's anything I can help out with.

This sounds reasonable. @aslonnie do you have a plan to support 3.13 image? Thanks.

around ray summit. the python dependencies need to be sorted out and tested first.
