feat(ci): publish dev-branch preview to :dev-latest

Per-version dev build publishes to the :dev-stable intermediate tag; the
composite job reads that for the stable slot and production tags for
older versions, producing the aggregated :dev-latest. Uses stable's
crowdin translations for the dev build.
