Add Docker Hub login to release workflow

Add docker/login-action@v2 steps to .github/workflows/release.yml across the release jobs so the workflow authenticates to Docker Hub before extracting metadata and creating/pushing manifests. The steps use DOCKERHUB_USERNAME and DOCKERHUB_TOKEN secrets to enable pushing images/manifests to Docker Hub.
