We use the Docker Hub Workflow to build and push our images to Docker Hub, but to check if we have vulnerabilities in our images as well. When we are just checking for vulnerabilities, we don't need to do all the builing steps. This commit optimizes the workflow by only doing the necessary steps when we are just checking for vulnerabilities, so during pull requests without label "preview" we skip the build steps, and we do not activate QEMU.
