Subject: [PATCH] ci: enable DOCKER_BUILDKIT for BuildKit FROM --platform
 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Gitea Dockerfile uses FROM --platform=$BUILDPLATFORM which requires
BuildKit. The GCE runner defaults to the legacy builder — set
DOCKER_BUILDKIT=1 to enable it.
