Youtube Video autoplay

Problem/Motivation

Youtube videos won't autoplay unless you configure sound to mute

Steps to reproduce

In field display, you can configure autoplay and responsive option

Proposed resolution

I propose to add a checkbox with mute option or simply add 'mute' => '1' in case autoplay is checked

This code is visible in src/plugin/video_embed_field/Provide/YouTube.php

public function renderEmbedCode($width, $height, $autoplay) {
    $embed_code = [
      '#type' => 'video_embed_iframe',
      '#provider' => 'youtube',
      '#url' => sprintf('https://www.youtube.com/embed/%s', $this->getVideoId()),
      '#query' => [
        'autoplay' => $autoplay,
        'start' => $this->getTimeIndex(),
        'rel' => '0',
        'mute' => '1',
      ],
