Improve documentation for Line Emission

• Improve documentation in line emission example notebook
• Rerun script to verify it runs end to end

We should not skip tests, especially not this one.

The idea of this test, was to have a very simple PINOCCHIO run, small enough that it can complete on GH runners. If it's still to slow, we should reconfigure it instead.

@deiruch Since we agreed on removing PINOCCHIO, I have skipped its test for this PR. Once this is merged, I will submit a new PR for the removal of the code and its tests.
