Replace "affectation" by "assignment" throughout the tutorial
"Affectation" cannot be used in English for a programming tutorial, as the meaning is completely different ("unnatural pose or mannerism", basically).
Only "assignment" works. I have a local branch ready for a MR solving this issue (pre-hook commit applied) but am, of course, not a maintainer of the project.
