To build the per-platform tag list, MANIFEST_DIGEST is taken from index.json and used to open that manifest’s blob, then .manifests[] is queried from that file. For a standard OCI layout this blob is a single image manifest and contains no manifests array, so IMAGE_DIGESTS is empty and --tag-platform-images never tags any platform images. The per-platform digest list should be derived from index.json itself rather than a child manifest.

Add a `tag_platform_images` attribute to `oci_push`, which if enabled,
results in each platform specific image being tagged with each remote
tag and an additional '-${os}-${arch}' suffix. This makes it possible
to reference platform specific images as `${tag}-${os}-${arch}`
(e.g. "v1.2.3-linux-arm64").
This makes it easier to use rules_oci and multi-image indexes, with
systems that do not handle OCI image indexes (such as AWS Lambda)
and instead require a reference to a platform specific image.
