fix(KFLUXBUGS-1601): use the base image name label to get its tag

[dirgim]

• The BASE_IMAGE result from the inspect-image task is supposed to be referenced by digest and is supposed to be used as such in other checks within the fbc-validation task
• Switch to extracting the base image name from the org.opencontainers.image.base.name for the needs of getting the base image tag and deriving the OCP version from it
