Feature request description

From Podman Desktop POV, we're displaying images.

We would like to display as well multi-arch images. These images are part of the libpod/images/json enpoint

But then, currently there is no way to know if the image being listed is a true image or part of a manifest.

From Podman Desktop, we need to know when image is a multi-arch to let the people know the arch/os of the manifest.

Suggest potential solution

include either manifests field corresponding to something like manifest inspect result

{
    "schemaVersion": 2,
    "mediaType": "application/vnd.oci.image.index.v1+json",
    "manifests": [
        {
            "mediaType": "application/vnd.oci.image.manifest.v1+json",
            "size": 1930,
            "digest": "sha256:94d0d9c033b913aba7b23976bcedfbda80cd6fbfa5abf605484f1eabf225a03a",
            "platform": {
                "architecture": "amd64",
                "os": "linux"
            }
        },
        {
            "mediaType": "application/vnd.oci.image.manifest.v1+json",
            "size": 1933,
            "digest": "sha256:e351b67dc93670018f56c891dc0e49d8bd6b99813e567170310446f89a61ca8b",
            "platform": {
                "architecture": "arm64",
                "os": "linux"
            }
        }
    ]
}

in that case, it means that Podman Desktop with one query to the list endpoint is able to grab all arch/os of image manifests

other option

include a boolean field like isManifest: true or Manifest:true

then we know it's a manifest and we'll need to query for each matching manifest/image a call to the Manifest API endpoint to know more about images

We're also fine if for example we need to include a parameter like ?showMoreThings on the endpoint
