title: how to sort case insensitive using jq
body: <p>Does <code>jq</code> support case insensitive sorting?</p>
  <p>for instance I have <code>data.json</code> like this</p>
  <pre class="lang-json prettyprint-override"><code>[
    {&quot;title&quot;: &quot;first&quot;, &quot;description&quot;: &quot;foo&quot;},
    {&quot;title&quot;: &quot;Second&quot;, &quot;description&quot;: &quot;bar&quot;}
  ]
  </code></pre>
  <p>simple <code>jq 'sort_by(.title)' data.json</code> returns</p>
  <pre class="lang-json prettyprint-override"><code>[
    {&quot;title&quot;: &quot;Second&quot;, &quot;description&quot;: &quot;bar&quot;},
    {&quot;title&quot;: &quot;first&quot;, &quot;description&quot;: &quot;foo&quot;}
  ]
  </code></pre>
