Fix wrong destructuring property in Expo.Audio.Sound.create example

`Expo.Audio.Sound.create` returns a [`Promise` that resolves to an object with `sound` as a property](https://docs.expo.io/versions/v28.0.0/sdk/audio#sound--the-newly-created-and-loaded), but the example tries to destructure with the key `soundObject` which will always be `undefined`.

Fix: use `sound` for the destructuring assignment and rename it to `soundObject` so that it's consistent with the other examples.

Closes expo/expo-docs#315
