ci/main-green: parse ci.yml with the declared js-yaml package (#13955)

validate-release-green imported the yaml package, which is not a
direct dependency on main. The nightly job then crashed before the
verdict fence, so the tracker comment was empty. js-yaml is already
declared and load() is the same parse for this workflow YAML.
