Github registry doesn't support digest yet, we need to download the manifest and calculate the digest manually Also fixing a few other issues: * Multi-stage dockerfiles override /usr/local/lib, moved jq and reg to /kaniko instead * The digest was fetched for the current tag, which doesn't exist yet. Fetching digest for the latest tag instead
