Summary:
Improve the error message shown when you try to nest components in an
`<Image>` component by referencing the `<ImageBackground>` component.
It would be helpful if the error message displayed when you try to nest components in an `<Image>` component mentioned the `<ImageBackground>` component. Especially since this component is not yet well documented.
[IOS][MINOR][Libraries/Image/Image.ios.js] - Surfaced `<ImageBackground>` in error message
[ANDROID][MINOR][Libraries/Image/Image.android.js] - Surfaced `<ImageBackground>` in error message
