python:3.14-slim doesn't ship curl or wget. The previous voice-download step assumed it did and failed with "curl: not found" (exit 127) in build stage 8. Replaced with a Docker BuildKit heredoc that runs python3 directly, using urllib.request.urlretrieve. Python is already installed (it's the base image), so this needs no additional apt packages and keeps the image footprint identical. The `# syntax=docker/dockerfile:1` directive at the top of this file already pulls in a BuildKit frontend that supports heredoc syntax. The download itself is unchanged: en_US-amy-medium and en_US-ryan-medium into /opt/piper-voices, with both .onnx and .onnx.json sidecar files.
