The quay.io/skopeo/stable image's entrypoint is `skopeo`. GitLab CI
runs job scripts via `<entrypoint> sh -c "<script>"`, so the resulting
invocation is effectively `skopeo sh -c ...`, where skopeo parses `sh`
as a subcommand and fails on the unrecognized `-c` flag:

  time="..." level=fatal msg="unknown shorthand flag: 'c' in -c"

Override the entrypoint to an empty list so GitLab CI can run sh
directly:

  image:
    name: quay.io/skopeo/stable:v${SKOPEO_VERSION}
    entrypoint: [""]
