Subject: build(docker): add pinned dev and docs images

garmin-otp/dev: Ubuntu 22.04 (pinned by digest; the simulator needs
WebKitGTK 4.0), apt packages from a dated snapshot.ubuntu.com mirror,
OpenJDK 17, Xvfb/openbox/noVNC for the headless simulator, the
connect-iq-sdk-manager CLI v0.8.4 checked against its release SHA-256,
and Python tools installed from a hash-locked requirements file.

garmin-otp/docs: Node 22 (pinned by digest), Debian snapshot packages,
markdownlint-cli2 and mermaid-cli from package-lock.json, and the
headless Chrome build pinned by Puppeteer.

Locks only use releases published before 2026-10-01. The Garmin SDK,
device files and the developer key are never baked into an image.

+# garmin-otp/docs: documentation checks for `make docs`.
+#   * markdownlint-cli2 lints every Markdown file.
+#   * mermaid-cli renders every Mermaid diagram to SVG (build/docs/), which
+#     proves the diagrams parse; it drives a headless Chrome through Puppeteer.
+#
+# Reproducibility: the Node base image is pinned by digest, Debian packages come
+# from a dated snapshot, npm packages install from package-lock.json (resolved
+# from releases published before the cutoff date in the Makefile), and the
+# headless Chrome build is the one pinned by that Puppeteer version.
