[iOS] [Fixed] - Fix NSAppTransportSecurity being overwritten during pod install

Pull Request resolved: https://github.com/facebook/react-native/pull/41875

Test Plan:
1. Delete the whole `NSAppTransportSecurity` in Info.plist and run `pod install`: `NSAllowsArbitraryLoads` and `NSAllowsLocalNetworking` are added as expected.
2. Modify `NSAppTransportSecurity` to only contain `NSExceptionDomains` and run `pod install`: `NSAllowsArbitraryLoads` and `NSAllowsLocalNetworking` are added, and `NSExceptionDomains` is still there.
3. Run `pod install` again: nothing changes.
