Creates a manifest list for a multiarch docker image and publishes it so that
users can pull an image using a generic name and the variant for their machine
architecture is automatically selected.

Usage:
$(basename $0) <tag>

Where:
  <tag> is something like "latest" or "v1.0.0".

An image for each of the supported architectures must have already been built
and published with <tag>.
