The commit adds steps to build and push a Docker image using Buildx in the GitHub Actions workflow. It includes checking out the repository, installing the cosign tool, setting up Docker buildx, logging into the Docker registry, extracting metadata for Docker, and finally building and pushing the Docker image with the specified tags and platforms. The commit ensures that the image is only pushed when the event name is not a pull request.
Changed the repository for pushing the docker image to GHCR from `ghcr.io/cp6/my-idlers` to `ghcr.io/hra42/my-idlers-arm64` in order to align with the updated repository naming convention.
This commit updates the tags in the GitHub Actions workflow for building Docker images. The previous tags `ghcr.io/cp6/my-idlers` are replaced with `ghcr.io/hra42/my-idlers-arm64`. This change ensures that the correct tags are used for the Docker image.
