[ci] Build and publish cu130 ray and ray-extra images (#63972)

## Description

`cu13.0.0-cudnn` is listed in `PLATFORMS_RAY` (`ray-images.json`), so
the nightly image verification (`check_nightly_ray_commit`) expects
`rayproject/ray:nightly-cu130` and `nightly-cu130-aarch64` to exist. But
the build/publish pipeline only produced images up to `cu12.9.1`, so the
cu130 tags were never pushed and verification failed at the `docker
pull` step:

```
docker_tags_lib.py: 111  Pulling image rayproject/ray:nightly-cu130
# -> 404, tag not found
```

This PR enables cu130 across both architectures and both image types so
the tags are actually built and published:

- **`.buildkite/build.rayci.yml`** (x86_64): add `13.0.0-cudnn` to
`ray-image-cuda-build` and `ray-extra-image-cuda-build`; add `--platform
cu13.0.0-cudnn` to `ray_images_push` and `ray_extra_images_push`.
- **`.buildkite/linux_aarch64.rayci.yml`**: add `13.0.0-cudnn` to the
`raycudabase-aarch64` and `raycudabaseextra-aarch64` base images (the
x86_64 bases already had it), to the `ray`/`ray-extra` cuda image
builds, and to the corresponding push steps.

No change to `ray-images.json` — `PLATFORMS_RAY` already lists
`cu13.0.0-cudnn`; this PR makes the pipeline match it.

## Additional information

- Both YAML files validate, and no test parses these configs for
consistency.
- The upstream `raycudabase*` cu130 base images already build for
x86_64; the aarch64 bases are added here so the `depends_on($)` fan-outs
resolve.
- Real validation is the first nightly build after merge (CI-only
change).
