Update docker-build-scan workflow

We changed that reusable-workflow this week adding support for
specifying multiple tags. Then the `tag` parameter is now `tags`, and you
can set multiple image references separated by `,`. Also, optionally, you
can specify in tags the full image reference (registry/image:tag) and
not only the tag, if you prefer.
