In email_auth_code.html.twig, we need to replace the picture URL by using asset

<td style="padding: 20px;" width="96px" valign="top"><img class="image_fix" src="{{ wallabag_url }}/themes/material/img/logo-other_themes.png" alt="logo" title="{{ wallabag_url }}" style="width: 96px; height: 96px;" /></td>
