Remove unused audio cues

[hediet]

These audio cues do not seem to be used:

vscode/src/vs/platform/audioCues/browser/audioCueService.ts

Lines 362 to 380 in d40162d

	public static readonly chatResponseReceived1 = AudioCue.register({
	sound: Sound.chatResponseReceived1,
	...this.chatResponseReceived
	});
	public static readonly chatResponseReceived2 = AudioCue.register({
	sound: Sound.chatResponseReceived2,
	...this.chatResponseReceived
	});
	public static readonly chatResponseReceived3 = AudioCue.register({
	sound: Sound.chatResponseReceived3,
	...this.chatResponseReceived
	});
	public static readonly chatResponseReceived4 = AudioCue.register({
	sound: Sound.chatResponseReceived4,
	...this.chatResponseReceived
	});

They appear in Help: List Audio Cues and I'm sure the sound files blow up the installer size.

these are used when this is invoked

vscode/src/vs/platform/audioCues/browser/audioCueService.ts

Line 60 in d7bdb0a

public playRandomAudioCue(groupId: AudioCueGroupId, allowManyInParallel?: boolean): void {

Ahh, what threw me off are the 0 references:

I think we should allow audio cues to have random sounds, getting rid of the groupId.
