Articles are not imported properly

[obuisard]

The workflow tables must be filled up or else articles won't show.

From conversation on Mattermost:

Information needs to be added to the asset table as well.

Use the Content model to properly insert data into those tables.

$factory = Factory::getApplication()->bootComponent('com_content')->getMVCFactory();
$content_model = $factory->createModel('Article', 'Administrator', ['ignore_request' => true]);

And save through the model
