Purpose of this commit is to add a publisher tour in standard that is not
only run using external tags. Indeed external tours are not monitored and
previous commits show that they can be broken since a long time.
In this commit we somehow copy the publisher tour with an article-based
slide instead of a video slide. That way it can be launched with other
standard tours.
