* Add top navigation to documentation (ray-project#30225)

This adds a top navigation to our documentation that will be unified with the top navigation of the ray.io website going forward so we can have a unified experience between ray.io website and documentation.

Before this is merged, @sijieamoy graciously offered to improve the styling of the top bar to fit better with the overall design. Currently the design is a placeholder with minimal work.

Update Kuberay version in CI. (ray-project#27967) (ray-project#29151)

Updates KubeRay version used in CI to v0.3.0-rc.2 (which we expect to be identical to the final v0.3.0).
Also removes a couple of old files.

Will open a corresponding cherry pick in the Ray 2.0.0 branch.
The key thing to verify is that the CI autoscaling test passes here and in the PR and in the PR against the 2.0.0 branch.
