Enable the default policy

Set BUILDX_DEFAULT_POLICY=1 to enable Buildx's built-in source policy. The policy verifies signed tags for images managed by Docker, including BuildKit builder images and Dockerfile frontends. Untagged digest references and images outside the managed repositories are allowed unchanged. Tagged references that also contain a digest still have their release identity verified.
