crane: Skopeo copy of gcr crane image fails with unknown media type

[davidrfreeman]

Describe the bug

When attempting a skopeo copy of the v0.14.0 image, it fails due to the following error

Unknown media type during manifest conversion: "application/vnd.docker.image.rootfs.diff.tar.gzip"

I believe this is related to this issue previously seen with a ko build of tekton
tektoncd/pipeline#5188

v0.13.0 does not have this issue

➜ skopeo copy --override-os linux --additional-tag gcr.io/go-containerregistry/crane:v0.14.0 docker://gcr.io/go-containerregistry/crane@sha256:4e0a096b2f61284e581a9e156e5595cebeccb074aa6289c593b352264279599d docker-archive:gcr.io-go-containerregistry-crane-v0.14.0.tar

FATA[0004] copying system image from manifest list: creating an updated image manifest: Unknown media type during manifest conversion: "application/vnd.docker.image.rootfs.diff.tar.gzip"

Looking at the layers for the amd64 image, the manifest says it's an OCI formatted image, but there are Docker layers in the manifest.

➜ crane manifest gcr.io/go-containerregistry/crane:v0.14.0 | jq '.manifests[] | select(.platform.architecture | contains("amd64")) | .digest' | xargs -I{} crane manifest gcr.io/go-containerregistry/crane@{} | jq '.layers[] | select(.mediaType | contains("docker"))'
{
  "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
  "size": 98,
  "digest": "sha256:72164b581b02b1eb297b403bcc8fc1bfa245cb52e103a3a525a0835a58ff58e2"
}
{
  "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
  "size": 8410379,
  "digest": "sha256:6ff4dd532debff59c2a7155e3f2556fd43461c7f09814c6d9b1a172eccaca00d"
}

To Reproduce

Copy v0.14.0 using skopeo version 1.11.1

Expected behavior

A skopeo copy successfully copies the image, with all layers being OCI formatted.

Additional context

Add any other context about the problem here.
