Fix AppDelegate not passing props in bridgeless and rename getBundleURL (#41169)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/41169

* `initialProperties` should be based on `prepareInitialProps`, not `launchOptions` (which don't seem to have an equivalent in bridgeless)
* `getBundleURL` is not idiomatic Objective-C (eg https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/CodingGuidelines/Articles/NamingMethods.html), so rename to `bundleURL`
