Obviously the edgiest of edge cases 😄
But I think this does the wrong thing if we have a nested index? e.g. if we have oci indexes nested inside an oci index? In that case, we should still use the oci type.

Hum right we don't handle nested indexes in addDesc atm

What about this as an alternative: we should check for a prefix of application/vnd.docker to see if all the types are docker types, then use a docker manifest list in that case. If they are all OCI or even just mix-and-matched, then we should default to OCI.

As discussed yesterday, I'm fine defaulting to OCI.
When using imagetools create and combining multiple sources we should check the media type of each manifest and set the right media type for the manifest list. If there is a mismatch we set OCI index as best effort. Signed-off-by: CrazyMax <crazy-max@users.noreply.github.com>
