Address review on #125371: the binding test passed the script-level
-NonInteractive alongside the alias, so deleting the fold line kept it
green. The new test runs -Stage setup -Json with only -SkipSetup and
asserts the skipped/needs-user-input frame, which only the fold can
produce (without it the stage dispatches interactively and fails under
a non-interactive host). Also document the deprecated alias in the
zh-Hans windows-native guide, which still said -SkipSetup is rejected.
(cherry picked from commit b97fc4561af918910b8b2b9bf728e501b89aeb27)
