Tutorials: Fix typo and split cell that retrieves results (backport #598)

[mergify[bot]]

This fixes a typo and splits the cell so that the results are retrieved in their own cell. This is nice because then the user will have a cell complete once all jobs are submitted and another complete when all results are available. I also removed an outdated reference to the old "commented block."
