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

Add the --load flag to the docker buildx build command and ensure you are building for only a single architecture \(e.g., --platform linux/amd64\). The local Docker daemon cannot load multi-architecture manifests.

Journey Context:
A developer upgrades their build pipeline to use docker buildx to create cross-platform images. They run docker buildx build -t myimage:latest --platform linux/amd64,linux/arm64 . and the build succeeds, but docker images shows nothing locally. They try adding --output type=docker but get the 'manifest lists' error. They spend hours trying to parse BuildKit output syntax and trying different local registry setups, thinking their local Docker daemon is corrupted. The reality is that the local Docker daemon is single-architecture and cannot ingest a multi-arch manifest list \(a JSON mapping of architectures to digests\). To load the image into the local daemon for testing, they must restrict the build to a single platform and use --load, reserving multi-platform builds for direct pushes to a registry via --push.
