title: How to set lang attribute on html element with Nuxt?
body: <p>Using the file <code>nuxt.config.js</code> file, <code>head</code> contents can be customized to add some meta, or other things:</p>
  
  <pre><code>module.exports = {
    /*
    ** Headers of the page
    */
    head: {
      title: 'awesome title',
      meta: [
        { charset: 'utf-8' },
        { name: 'viewport', content: 'width=device-width, initial-scale=1' },
        { hid: 'description', name: 'description', content: 'Nuxt.js project' }
      ],
      link: [
        { rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
      ]
    },
    ...
  }
  </code></pre>
  
  <p>But I can't find anything in the documentation to set attributes on the <code>html</code> element -- I want to set the <code>lang</code> attribute. Is there a way to do that?</p>
