Typo: Incorrect URL to Nested Iteration section in FOPP Project LIst

[BergProfJ]

Describe the bug In the FOPP table of contents (https://runestone.academy/runestone/books/published/fopp/index.html), under the "Project List" section: the "Skills required" list for the "Image Processing" project lists "Nested Iteration" with a URL that doesn't direct to the proper URL.

To Reproduce Steps to reproduce the behavior:

1. Go to 'https://runestone.academy/runestone/books/published/fopp/index.html'
2. Look at the Project List section
3. Scroll down to 'Image Processing...Skills required"
4. Note that URL for "Nested Iteration" refers to Ch 14 ("More About Iteration") instead of Sec 7.8 ("Nested Iteration: Image Processing")

Expected behavior URL expected (I believe):
https://runestone.academy/runestone/books/published/fopp/Iteration/NestedIterationImageProcessing.html

URL that appears incorrectly: https://runestone.academy/runestone/books/published/fopp/MoreAboutIteration/toctree.html

Screenshots If applicable, add screenshots to help explain your problem.
