[GHA] "prerelease" flag isn't properly forwarded between jobs to publish to 3rd party stores

Is your request related to a problem? Please describe.
It seems that we forgot to update the docker alpha image in the action that publishes GAMA.

Describe the improvement you'd like
When a new alpha is built by the github action, in addition to all the publication, we should push a new docker version (alpha or latest depending on tags)

Additional context
Discovered thanks to feedbacks in #352

That's not really an error : while generating (pre-)release, the workflow offers to make it only for Github, or to broadcast the release everywhere. Since, recently, we're making releases only for Github, the docker workflow is never triggered 🤷

So it's just the normal way things works.

Now the real question is, do we want to have the docker alpha matching the github alpha (i.e. give the option to make pre-release only available in "our stores" (github, docker) or every stores (homebrew, ppa, windows, etc)).

Maybe it's just a problem of parameter names. For the last release I gave in example, I think I didn't pick "stable release" nor "publish only on github", you can check it there idk how to get the parameters I picked but you can see that it's pushed to windows store.
Now I have no idea what I should have picked to publish it also on docker, is it automatically skipped if it's not a stable ?

Ok I identified it, indeed it's a bug.

The condition needs.get-tag-info.outputs.prerelease == 'true' isn't checked as some step's output are not properly forwarded between steps (you can see some steps skipped too in the Windows one)... And after a fresh look at it, it's strangely built too, so I'll rework it :)
