Summary
This PR fixes the misleading documentation in
getting-started.mdthat incorrectly stated Metro bundler would open automatically when runningnpx react-native run-macos.As confirmed in issue #2208, Metro bundler must be started separately before running the app and this is expected behavior by design. Users following the current documentation were encountering the error "No script URL provided. Make sure the packager is running or you have embedded a JS bundle in your application bundle" because they expected Metro to start automatically.
