Remove TextAncestor import from rn-tester TextExample (#51603)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51603

In `rn-tester` TextAncestor was used to create a inlineView wrapper:

```js
function InlineView(props) {
  return (
    <TextAncestor.Provider value={false}>
      <View {...props} />
    </TextAncestor.Provider>
  );
}
```

however, it is already done in View.js and TextAncestor shouldn't be used outside of react-native package:

```js
 if (hasTextAncestor) {
    return <TextAncestor value={false}>{actualView}</TextAncestor>;
  }
  return actualView;
```
