The shared _publish_multiarch_manifest() helper always derived a
"-job-dispatcher" registry from the registries it was given. However, the
dispatcher is a kata-deploy-specific sidecar image, so when the helper
was reused to publish the kata-monitor multi-arch manifest it wrongly
tried to push a non-existent kata-monitor-job-dispatcher image.
Let's gate the dispatcher derivation behind
KATA_DEPLOY_PUBLISH_JOB_DISPATCHER (defaulting to true so the
kata-deploy path is unchanged) and opt out of it when publishing the
kata-monitor manifest.
