Reported version is wrong

[achingbrain]

We report the deployed version of the bootstrapper on the dashboard:

It's always one version behind the latest npm release, because publishing the docker container takes place in a different GH workflow to publishing the npm module, and you can't make one workflow depend on another.

We solved this problem ages ago for js-ipfs - the js-test-and-release workflow logs us in to a docker registry before calling npm run release, and then we'd do the npm release and the docker push from npm scripts, e.g.:

{
  "scripts": {
    "release": "npm run release:npm && npm run release:docker",
    "release:npm": "... do npm things",
    "release:docker": "... do docker things"
  }
}

Perhaps we should do something similar here?
