RadioButton.Item - Android Talkback can reach radio button twice

### Current behaviour
If you use the Android Talkback screenreader to navigate the radio button, you first hit the label + radio button (as intended with `RadioButton.Item` - but then the screen reader can also reach the radio button itself, which is unlabelled. This is undesirable, as it's both confusing, and requires extra swiping.

### Expected behaviour
Radio button should not be reachable on its own when used within a `RadioButton.Item`.

### How to reproduce?
Create a `RadioButton.Item` and test it out with Android Talkback.
