Deployer Docker image missing linux/arm64 manifest #300
Description
The ghcr.io/spotify/confidence-cloudflare-deployer:latest image only includes a linux/amd64 manifest, causing it to fail on ARM-based machines (e.g. Apple Silicon Macs):
docker: Error response from daemon: no matching manifest for linux/arm64/v8 in the manifest list entries: no match for platform in manifest: not found
Workaround: Pass --platform linux/amd64 to force emulation.
Request: Add a multi-arch build (amd64 + arm64) to the deployer image.
