Fix release deploy: use a Node-based image so checkout's JS action runs

docker:27-cli is Alpine with no Node.js, but actions/checkout@v4 is a
JS action that needs a Node runtime in the job container — it failed
at Checkout with exit 127. node:22-bookworm-slim already has Node
(same reason the test job's node:22-alpine works); Docker CLI and
openssh-client are added via apt instead.
