But do we want to add the `3.2` tag for a `3.2.10-rc1` image? That means
that users who specify `3.2` and were previously on an official release `3.2.9`
that they now get a release candidate version.
IMO release candidate images should only have their full version as a
Docker tag and not something like `3.2` as that usually implies a stable
version.
