katacoda runner: group tutorials into topics

[GuentherJulian]

Katacoda offers the possibility to group tutorials into courses (https://www.katacoda.community/git-repository-structure.html#courses).
If we have several tutorials on the same topic (e.g. devon4g), we could group them. This way the katacoda account would be clearer.
Probably we need to pass this topic through the playbook and the parser needs to be adapted for this.

Let's not focus on this right now but possibly we can already share some thoughts on it. There seems to even another notion of scenarios, am I right? So scenarios could be something like what @SchettlerKoehler finally plans to do? We currently are implementing trainings? And what about courses? In any case let's align together what we would expect from each of the different things and what's the difference between them from a katacoda technical standpoint.

@maybeec At the moment we are creating single tutorials (scenarios in katacoda language). Courses are a way to group multiple scenarios together. For example, we have a course about devon4j and we group all tutorials related to devon4j in this course. In Katacoda itself, it's just a way to display them. In the main page, we have a course and when we open it, we can see all the tutorials that belong to it. But we need to change the structure of the tutorials on Github.

If we implement the restoreWorkspace command, maybe we could implement a tutorial series where each tutorial could start with the state of the last tutorial.

It should group the tutorials based on a course_[name].json file. Add a prebuild to group them automatically
