Summary:
I noticed that there was a `height` and `width` props in `Image` component, but those props are not being used in `RCTImageView`(ios) or `ReactImageView`(android).
## Changelog
[GENERAL] [Removed] - Remove Unused ImageProp
Pull Request resolved: https://github.com/facebook/react-native/pull/28151
Test Plan: Start a new React Native Project, and use `Image` component with `width` and `height` props and verify that it does not display the image on both iOS and Android
