[docs] update Column generation tutorial

[odow]

I'm giving a few tutorials in October at https://cermics-lab.enpc.fr/seso2023/ and https://julia-users-paris.github.io/workshop/en/.

My plan is to work through a few of these examples, with little exercises at the bottom for people to try. I think it makes sense to add these to the JuMP documentation.
