@discordjs/voice example is incorrect

### Which package is this bug report for?

voice

### Issue description

See: https://github.com/discordjs/voice-examples/blob/266d250d34abf352b320be1781b6f39146eefcb3/radio-bot/src/bot.ts#L105

ISSUE: Bot will never begin playing audio because the "player" object will never emit 'stateChange'

PERCEIVED CAUSE: A state change is not being emitted until "player.play()" is called, which will emit the stateChange event that performs "attachRecorder()".

In the example, the following code is as follows:
```
const connection = await connectToChannel(channel);
connection.subscribe(player);
await message.reply('Playing now!');
```

Although a subscription is added, that in itself is not enough to emit a state change or cause the player to begin playing. In the example, following connection.subscribe(player), a new line with "player.play()" should be added.

Start at radio-bot/src/bot.ts around line 105 and review the sequence after connection.subscribe(player). Run the radio-bot example to confirm that the bot begins playing audio and that the recorder setup is reached when playback starts.
