Docker Hub is missing the -0 suffix on the first image for a tag

only creates higher-level tags, so if this repository is tagged with 5.14.0 instead of 5.14.0-0 the Docker Hub tags 5.14.0 and 5.14 are created, and 5 is updated.

If the image is later rebuilt and tagged as 5.14.0-1 Docker Hub tags 5.14.0, 5.14 and 5 are updated, but since there was never a 5.14.0-0 tag the original 5.14.0 image is lost.

This also applies to https://hub.docker.com/r/openmicroscopy/omero-server/tags

Thanks for the info.
Are you working on that issue in the action?

Checking https://github.com/jupyterhub/action-major-minor-tag-calculator/blob/main/README.md
Pushed reference "1.2.3-4" => tags output "[1.2.3-4, 1.2.3, 1.2, 1, latest]"

No, I think this is best handled when the GitHub *-docker repository is tagged. Extrapolating a release tag of 5.14.0 to 5.14.0-0 is doable, but since rebuilds of the Docker image will need a -1, -2, ... etc GitHub tag anyway it seems more consistent to start with a -0 GitHub tag.
