Update RNTester AppDelegate for changes made to SurfacePresenter API (#28580)

Summary:
This pull request updates RNTester's AppDelegate's Fabric mode to reflect changes made to the SurfacePresenter APIs. It now makes use of `RCTSurfacePresenterBridgeAdapter` to create its `SurfacePresenter`.

## Changelog

[Internal] [Fixed] - Fixed outdated API usage in RNTester's AppDelegate
Pull Request resolved: https://github.com/facebook/react-native/pull/28580

Test Plan: `RNTester/RNTester/AppDelegate.mm` now compiles without error when `RN_FABRIC_ENABLED` is enabled.
