clock vibrate on tap

[AlexanderBlank]

When using the lichess mobile app's clock tool, for timing over the board games,
it would be nice if there was a short vibration when a player taps the clock,
similar to how other, non-free, Android chess clock apps have this as an option, or like how the metal touch buttons on a physical Chronos chess clock vibrate when tapped.

@veloce is this as simple as adding vibrate.tap() to clockTap in ChessClockCtrl?

lichobile/src/ui/clock/ChessClockCtrl.ts

Lines 37 to 40 in 0cf577a

	function clockTap(side: 'white' | 'black') {
	clockObj().clockHit(side)
	currentMove += 0.5
	}

Is this the appropriate place to perform a vibrate.tap()? This would not create a new setting, but rather reuse the existing Notification setting of whether or not to vibrate on game events.
