配置项fastForward设置为true时长按快进报错

[WhiteSevs]

Expected behaviour

Actual behaviour

Steps to reproduce

启用移动端长按快进

fastForward: true

报错如图

经排查是这里的错误，当触发快进时播放速度为Artplayer.FAST_FORWARD_VALUE = 3，该速度不在Artplayer.PLAYBACK_RATE = [0.5, 0.75, 1, 1.25, 1.5, 2]里，就是空的

ArtPlayer/packages/artplayer/src/setting/playbackRate.js

Lines 12 to 15 in 714c81e

	function update() {
	const target = art.setting.find(`playback-rate-${art.playbackRate}`)
	art.setting.check(target)
	}

Environment

• Browser: Edge
• Version: 140.0.3485.54
• Operating System: Windows
• Version: 11

Console errors (if any)

Uncaught TypeError: Cannot read properties of null (reading '$parent')

😂我也遇到过，但是能正常用就一直没管，感觉webjs报些错很正常。
