feat: added enterKeyHint prop to textInput (#34482)

Summary:
This adds the `enterKeyHint` prop to the TextInput component as requested on #34424, mapping web [enterKeyHint types](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/enterkeyhint) to equivalent [returnKeyType](https://reactnative.dev/docs/textinput#returnkeytype) values. This PR also updates RNTester TextInputExample in order to facilitate the manual QA.

## Open questions
 - What should be the `returnType` in the case of `previous` in iOS?

 - what should happen if `enterKeyHint` and `returnKeyType` props are passed together?

## Changelog
[General] [Added] - Add enterKeyHint prop to TextInput component

Pull Request resolved: #34482

Test Plan:
- Open the RNTester app and navigate to the TextInput page
 - Test the TextInput component through the `enterKeyHint modes section`
