Use a single custom annotation for export

Browse Source 
Remove annotation prefix and add multiple index records
for manifests with multiple image names. This makes the
custom annotation more consistent with the OCI image
annotation. Additionally, ensure the OCI image annotation
always represents the tag (partial image name) as recommended
by the specification. The containerd image name annotation
will always contain the full image name.
