Since docker hub stopped Autobuild, we need to switch to something else.
This will trigger building of images on Github Actions and pushes them
to Docker Hub.
You only need to add 3 secrets before you merge this PR to have it working directly.
- DOCKERHUB_USERNAME : The username of the account you are going to push the builds to
- DOCKERHUB_TOKEN : The token needed to login and push builds
- DOCKERHUB_REPO : The repo name in the following form `index.docker.io/<user>/<repo>`
So for vaultwarden that would be `index.docker.io/vaultwarden/server`
Also some small modifications to the other workflows.
