fix: deep and universal links

[okwasniewski]

Summary:

This PR allows to use deeplinks/universal links in React Native visionOS apps.

In order to use this feature, users need to add this modifier to their App.swift file:

@main
struct RNTesterApp: App {
  @UIApplicationDelegateAdaptor var delegate: AppDelegate
  
  var body: some Scene {
    RCTMainWindow(moduleName: "RNTesterApp")
      .onOpenURL(perform: { url in
        RCTLinkingManager.onOpenURL(url: url)
      })
  }
}

A more in-depth documentation page will be created.

Thanks to @thiagobrez for investigating this one and helping me with the implementation and testing 🙏
