A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

There's a workflow that builds container images and publishes them to GitHub's container registry. However, even though there are version tags (and the build runs with those tags), the versioned tags are not published.

Describe the solution you'd like
A clear and concise description of what you want to happen.

It would be nice to have tags we can use, like: ghcr.io/postgresml/pgcat:1, ghcr.io/postgresml/pgcat:1.0.0, ghcr.io/postgresml/pgcat:1.1.0, etc.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

We can pin to a digest and always use the latest tag, but it's a lot less straightforward to know when a given release is "recommended" (users generally assume that tagged releases are better than "whatever the latest main branch build is")
