Project Wiki Content entries should be linked to their details page (to be editable)

Problem/Motivation

Currently Wiki Content Entries in the Wiki are handled like the Markdown entries and are not linked to their details page.
But it would be important to link their title to the details page to make them editable!

We could also discuss adding action links in the bottom of these. Maybe Drupal has a built-in helper for that. (Please create a follow-up for that)
