Extension for the CMS Yellow

[GiovanniSalmeri]

Hello @manucaralmo. I have used your excellent code for an extension for the CMS Yellow: https://github.com/GiovanniSalmeri/yellow-analytics

Beside some technical adaptations and some esthetical changes, I have made small modifications for accessibility and added support for Matomo and Open Web Analytics. I have not yet published the code for Yandex Metrika:

    // Yandex Metrika
    if (this.tracking.YandexTagId) {
      let YandexData = document.createElement('script');
      YandexData.text = `
        (function(m,e,t,r,i,k,a)
          {m[i]=m[i]||function(){(m[i].a=m[i].a||[]).push(arguments)};
          m[i].l=1*new Date();k=e.createElement(t),a=e.getElementsByTagName(t)[0],k.async=1,k.src=r,a.parentNode.insertBefore(k,a)})
        (window, document, "script", "https://mc.yandex.ru/metrika/tag.js", "ym")
        ym(${this.tracking.YandexTagId}, "init", {});`;
      document.head.appendChild(YandexData);
    }

Please feel free to use these little changes and additions if you find them useful. Thank you!
