Report #85677

[bug\_fix] docker exporter does not currently support exporting manifest list

Use the \`--load\` flag with a single platform \(e.g., \`--platform linux/amd64 --load\`\), or use \`--push\` to push the multi-platform manifest to a registry.

Journey Context:
A developer tries to build a multi-architecture image locally using \`docker buildx build --platform linux/amd64,linux/arm64 -t myimage .\`. The build fails with an error about manifest lists. They try adding \`--load\` to the same command, but get the exact same error. They dig through buildx issues and realize the local Docker daemon cannot store a multi-platform manifest list \(a single image tag pointing to multiple architectures\). The fix works because \`--load\` is designed to import a single platform image into the local Docker engine, while multi-platform builds must be pushed directly to a registry where the manifest list can be properly stored and served.
