Make it easy to find how to start a workshop session

[elefevre]

I occasionnally use the workshop part of Paysage for small events at a primary school. Everytime, I have to remember the link (https://www.paysage.xyz/workshop/creature), which is very much a pain, as I usually do not have my main computer with me (I prefer to use older machines, in case a kid knocks them down).

My workaround is to go to my github page where I list recos for introducing kids to programming (https://github.com/elefevre/programmation-pour-les-enfants). But that does not work when I want to give a link to interested parents.

I would like to see maybe http://paysage.xyz offer a list of pointers, instead of opening a new "full fledged" playground.
