Issue Description

Currently, the registry operator and the registry helm chart support the usage of a storage enabled volume for the OCI registry path to be mounted on. This allowed OCI artifacts to persist across deployments of the registry. These OCI artifacts at this point are created from the source content on the devfile-index (registry server) image, therefore in addition with security challenges with OpenShift it is best that support for this feature is retired.

The registry operator field spec.storage.enabled should be deprecated and the helm chart field persistence.enabled should also be deprecated. The field spec.storage.enabled should be disabled by default in #1092.

Acceptance Criteria

• spec.storage.enabled should be disabled by default
• spec.storage.enabled should be marked as deprecated
• persistence.enabled should be marked as deprecated
• Update documentation to reflect these changes
