fix: typo in tutorial

I believe that is done on purpose, because in the past some people have accidentally tried to execute that on the interactive Python interpreter (>>>).

@Gallaecio Maybe but the others bash command in the same file don't have the $ sign. It is the only one.
So we must put a dollar before all bash command or none.

Oh, you are right! Well, consistency triumphs most things in my book :)
