Summary:
Currently, the documentation shows both `password` and `secureTextEntry` as props for TextInput. However, the `password` prop is only passed to the Android component, so it does not work as expected for iOS developers. This PR prefers `password` over `secureTextEntry` but won't break anybody's code.
