Fine-grained history and citation guidelines for each tutorial

[MakisH]

We currently tell people to cite the preCICE Distribution (data publication), but sometimes we also want to cite an academic publication for a specific test case. This information is kind of lost at the moment.

Suggestion:

• Add a "History and citing" section at the bottom of some tutorials
• Add a note for tutorials in the literature guide
• Later, add a "History and citing" to every tutorial

The history and citing section should include information also about solver-specific cases.
