title: Changing default header for JSON data in Gin
body: <p>I've noticed that using Gin to return a response like this:</p>
  
  <pre><code>c.JSON(http.StatusOK, jsonData)
  </code></pre>
  
  <p>automatically creates the following header:</p>
  
  <pre><code>application/json; charset=utf-8
  </code></pre>
  
  <p>Is it possible to modify the header somehow to just return</p>
  
  <pre><code>application/json
  </code></pre>
  
  <p>I'd rather take this approach than splitting the string at the <code>;</code></p>
