Remove Patching To TextInputExample.windows.js

The examples have some freestanding text inside of properties of a React Element (see "generic generic generic"). The dev-mode React renderer will throw when it sees this, explicitly checking that any text is surrounded by a Text element. This goes through only upstream code, so this will likely affect other platforms and is worth submitting a fix for.

 {
    title: 'Auto-expanding',
    render: function(): React.Node {
      return (
        <View>
          <AutogrowingTextInputExample
            enablesReturnKeyAutomatically={true}
            returnKeyType="done"
            multiline={true}
            style={{maxHeight: 400, minHeight: 20, backgroundColor: '#eeeeee'}}>
            generic generic generic
            <Text style={{fontSize: 6, color: 'red'}}>
              small small small small small small
            </Text>
            <Text>regular regular</Text>
            <Text style={{fontSize: 30, color: 'green'}}>
              huge huge huge huge huge
            </Text>
            generic generic generic
          </AutogrowingTextInputExample>
        </View>
      );
    },
  },

Open TextInputExample.windows.js and inspect the AutogrowingTextInputExample content shown in the issue. Remove the freestanding text outside Text elements, then verify that the example no longer triggers the dev-mode React renderer error.
