[bug\_fix] ERROR: docker exporter does not currently support exporting manifest lists

Append \`--push\` to push the multi-architecture manifest directly to a container registry, or build a single architecture at a time and use \`--load\` to save it to the local Docker daemon.

Journey Context:
A developer attempts to build a multi-architecture image locally using \`docker buildx build --platform linux/amd64,linux/arm64 -t myapp:latest .\`. The build succeeds but fails at the export step with the 'docker exporter does not currently support exporting manifest lists' error. They try \`docker images\` but don't see it. After reading BuildKit documentation, they learn that the local Docker daemon cannot store multi-architecture manifests \(manifest lists\) natively. To get the image, they must either build a single platform \(e.g., just \`linux/amd64\`\) and use \`--load\` to import it locally, or use \`--push\` to push the multi-arch manifest directly to a registry like Docker Hub or ECR.
