 The first Step will build the Image using a Builder Instance with the `docker-container` driver and push the image cache to the remote registry, as specified by `cache-to`, with additional cache export options being used to export all the layers of intermediate steps with the image manifests. More details cache export options [here](https://github.com/moby/buildkit?tab=readme-ov-file#registry-push-image-and-cache-separately).
