Bug: Your extension overwrites the meta fields in tl_news

[jankout]

Bug description

Your extension overwrites the meta fields in tl_news in Contao 4.11.x

Following fields disappear if I use your extension

_{meta_legend}, pageTitle, robots, description, serpPreview_

it would be better to use Contao\CoreBundle\DataContainer\PaletteManipulator;

Your _tlnews.php could be like this

<?php
use Contao\CoreBundle\DataContainer\PaletteManipulator;
/**
 * add global operation
 */
array_insert($GLOBALS['TL_DCA']['tl_news']['list']['global_operations'], 0, [

        #'button_callback' => ''
