Feature Request

Is your feature request related to a problem? Please describe.
Following the description to create detail page and list page I recognized that the requested Plugin "News System" doesn't exist anymore. Instead one has to select the content element called "News article list (incl. detail view)" for both, detail and list page. The screenshots have to be replaced. Now one doesn't have to specify "what to display" (since it is automatically selected by choosing News article list (incl. detail view)).

Describe the solution you'd like
In the description to create detail page and list page replace the sentence "Add a new content element and select the entry :guilabel:Plugins > News system" by "Add a new content element called News article list (incl. detail view)." Remove the mention about the :guilabel:What to display. Same for the list page. And replace the screenshots by the new screenshots.

Versions
In an instance of TYPO3 v13, News version: main, 12.
