Change Scroller getter to protected (#52387)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52387

I would like to grab this in a subclass but unfortunately can't. It is kinda jank since this is a val obtained via reflection, but I figure this is better than copy and paste. I think that I could also expose a function that uses this scroller the way I want it to. Let me know if there are strong objections here
