Ensure all non-Jupyter assets (e.g. images, scripts) are correctly linked

[adamkewley]

The Jupyter notebooks for the course were copied-and-pasted from their original location(s) and then any files etc. that didn't appear to be used inside the notebooks were deleted.

I was fairly careful about this, but it would be wise to:

• Go through each jupyter notebook
• Verify that each asset that's linked in the notebook's content is displaced in the jupyter UI without any loading issues
  • e.g. if an image is linked in the notebook's markdown content then rendering that block should result in an image being successfully loaded. If it doesn't load then the image is missing or the link is wrong.
• Verify that each click-able hyperlink actually jumps to a location that actually exists
  • e.g. if an external website has been subsequently deleted or shutdown then this should find that problem
  • e.g.2 if a notebook links to some other notebook via the old name, that should be fixed to link to the new name

L1 seems fine

I went through all content, the only links that are broken are bookmark ones that link to headers, which will be handled in #4
