SpawnSoundAtLocation - Update for Unreal 5.3

[raccoon]

If anyone uses Unreal 5.3 for this course, the SpawnSoundAtLocation signature seems to have changed.

I made it work like this:

	const FVector Location = Mesh->GetSocketLocation(TEXT("MuzzleFlashSocket"));
	const FRotator Rotation = Mesh->GetSocketRotation(TEXT("MuzzleFlashSocket"));

	UGameplayStatics::SpawnSoundAtLocation(
		GetWorld(),
		MuzzleSound,
		Location,
		Rotation
	);
