In the prod released v1.14.2 bundle we accidentally shipped a multi-arch manifest list image that contained reference to only single arch-ful (amd64) bundle image. As a result, users/clusters trying to upgrade/install the operator on non-amd64 arch always failed.

Note from Konflux: https://konflux.pages.redhat.com/docs/users/getting-started/building-olm-products.html#building-file-based-catalog-fbc-components:~:text=Bundle%20images%20SHOULD%20NOT%20be%20referenced,Index%20or%20manifest%20list%20is%20encountered - bundle image references should be single arch, i.e. either application/vnd.oci.image.manifest.v1+json or application/vnd.docker.distribution.manifest.v2+json types and not a manifest list image.

Acceptance criteria: Gating verify check in cert-manager-operator-release konflux pipeline to enforce checking that all bundle references in catalogs are single-arch image of type either application/vnd.oci.image.manifest.v1+json or application/vnd.docker.distribution.manifest.v2+json only.
