📜Adds info about public adventures to teacher guide (#5909)

Adds info to all the languages (did it the old fashioned copy/paste way, because I think boryana is still working on weblate). 

When doing this i found some weird yalms for some languages. I don't know if you already knew about this @Felienne, but:
kab: the whole yaml is upside down for some reason
ne & uz: does not have a teachers guide, whole sections missing
ta: empty file, just contains {}

Fixes #4955

-            You can duplicate the class on the 'For Teachers' page. If you duplicate a class, all the class settings are duplicated as well. This means that all the levels and adventures you've made unavailable for the first class will now be unavailable for the new class(es) as well.

-            In the class overview you can see which adventure your students are working on right now. You can see that one student is working on the 'Rock, Paper, Scissors' adventure in level 1, one is working on the 'Fortune Teller' in level 1 and one student is working on the 'Rock, Paper, Scissors' adventure in level 2.
-            If you'd like to know which of your students is working on the adventure, simply click the number and their accountnames will appear.
-            You can also see how many of your students have finished the quiz. In this case, one student finished the quiz in level 1. Again, you can click the 1 to see which of your students it is.

-            Congratulations on reaching the end of Hedy! Your students have now learned how to create their own basic code in the Python programming language.
-            Of course, you could keep programming in our Hedy compiler, but it might be more exciting for your students to transfer to a "real" Python interface.
-            Would you like to continue teaching Python? Then please visit <a href="https://www.python.org/about/gettingstarted/" target="_blank">the Python website</a> to learn how to get started in another compiler.

-            Now that your students have a basic knowledge of programming in general, you could also show them around in other textual programming languages. The language might change but the concepts do not, so Hedy will still give them a big advantage.
