Describe the bug

empty.Image is creating an empty container image with the obsolete mediaType application/vnd.docker.distribution.manifest.v2+json

To Reproduce

See related issue GoogleContainerTools/kaniko#3319

Expected behavior

Empty container images are created with current expected mediaType application/vnd.oci.image.manifest.v1+json.

Additional context

As a consequence of this bug, Kaniko images built from scratch get the obsolete mediaType application/vnd.docker.distribution.manifest.v2+json and get rejected by OCI-only container registries (like ZOT).
As mentioned above, the related Kaniko issue related issue GoogleContainerTools/kaniko#3319 gives much more context information.

I have been looking for the moment when Docker switch their default format from their legacy one to the current OCI one, but I could not find it. It is in any case not a very recent change.
