Include transform in OUTER_PROPS (#26611)

Summary:
Without `transform` in `OUTER_PROPS`, the refresh control component would not include `transform: {scaleY: -1}` in its style and so pulling down, rather than up, on a scroll view would trigger a refresh.

Fixes #26181

## Changelog
[Android] [Fixed] - Fixed issue with refresh control not working properly on an inverted ScrollView
Pull Request resolved: #26611
