[bug\_fix] docker buildx build --platform linux/amd64,linux/arm64 fails with 'multiple platforms feature is currently not supported for docker driver'

Create and use a docker-container driver for buildx \(e.g., docker buildx create --name mybuilder --use\), then bootstrap it \(docker buildx inspect --bootstrap\) before building.

Journey Context:
A developer tries to build a multi-architecture image for their M1 Mac to deploy to an AMD64 Linux server. They run 'docker buildx build --platform linux/amd64,linux/arm64 -t myimage .'. It fails immediately complaining about the driver. They try updating Docker, but the issue persists. They read the buildx documentation and discover the default 'docker' driver is deeply integrated with the existing Docker daemon and doesn't support multi-platform builds because it relies on the daemon's internal state. By creating a 'docker-container' driver, buildx spins up a dedicated BuildKit container that fully supports multi-platform builds via QEMU and cross-compilation, allowing the build to succeed.
