Subject: [PATCH] Add the missing setup_notebook() line to HowToGalaxy tutorial
 scripts

Every workspace/tutorial script opens with

    # from autogalaxy import setup_notebook; setup_notebook()

right after the module docstring; the line chdir's to the workspace root and
enables inline plotting when the generated notebook is run. A handful of
scripts never got it. Without it a tutorial that loads data by a relative path
(or shells out to a simulator) fails under nbconvert, which runs with CWD set
to the notebook's own directory, and works interactively only if the user
happened to launch jupyter from the repo root.

This is the full audit of every chapter in the repo (plus the root
start_here.py): the missing line is added in the sibling convention's exact
position and the generated notebooks are updated to match, uncommented, the
way PyAutoHands emits them.
