continuumio/miniconda3:latest manifest type Regression v2 to v1

[quantum-byte]

Hi everybody,

today i encountered issues since in the latest version of continuumio/miniconda3 the docker image manifest mediaType changed from v2 (application/vnd.docker.distribution.manifest.v2+json) in version 22.11.1 to v1 (application/vnd.oci.image.manifest.v1+json).

See also a diff between the respective docker manifest inspect command outputs

Was this intentional ? If not - Can and should you revert that ?

We are encountering this bug in kanico because of it.
It causes a failure when pushing a docker image based on continuumio/miniconda3:latest to fail with this error:
MANIFEST_INVALID: manifest invalid; mediaType in manifest should be 'application/vnd.docker.distribution.manifest.v2+json' not 'application/vnd.oci.image.manifest.v1+json'

At the moment we just put a workaround in place to pin the 22.11.1 continuumio/miniconda3 image version until we figure out if there is a better longterm solution.
