title: How to change default language in React-TinyMCE?
body: <p>I just installed and configured react-tinymce in my React JS Application. Everything work fine ! </p>
  
  <p>But, the user interface is in English, and my client would like to have it in French. So, I followed the advice on tinymce documentation, but I have this error message that appears in my text editor: "Failed to load plugin url: <a href="https://cloud.tinymce.com/5/langs/fr_FR.js" rel="nofollow noreferrer">https://cloud.tinymce.com/5/langs/fr_FR.js</a>" in a red block, and the interface is still in English. </p>
  
  <p>This is my code for this element:</p>
  
  <pre><code>     &lt;Editor
             apiKey='XXX'
             initialValue="&lt;p&gt;Contenu de l'information&lt;/p&gt;"
             cloudChannel='Default'
             init={{
               plugins: 'link image code table imagetools media ',
               toolbar: 'undo redo | bold italic | alignleft aligncenter alignright | code | table | image',
               language: 'fr_FR',
               images_upload_url: true,
             }}
  
          onEditorChange={this.handleEditorChange}
      /&gt;
  </code></pre>
  
  <p>Any ideas ? </p>
  
  <p>Thank you in advance</p>
