message: build(docs-infra): avoid race condition in `aio-builds-setup/` npm scripts
  Previously, due to multiple scripts re-building during `yarn dev`
  initialization, there could be race conditions that led to errors.
  This commit fixes it by ensuring `yarn build` is run once (before
  the main `yarn dev` script).
