error jb build

[lunebellec]

I tried to compile the book with a recent jupyter book and got the following error message:

The Table of Contents file is malformed: toc is not a mapping: <class 'list'>
You may need to migrate from the old format, using:

	jupyter-book toc migrate /home/pbellec/git/high_confidence_ad/content/_toc.yml -o /home/pbellec/git/high_confidence_ad/content/_toc.yml

after applying the suggested fix I still get a bunch of errors:

My book was built with Jupyter Book 10.0 and my Dockerfile froze the book at that version.

Newer versions of Jupyter Book use a different Table of Contents format.

Ooops I just noticed this is not in the PR for my book. Still, the comment might apply; if the Jupyter Book version isn't frozen, the ever-continuing changes in their new versions might break the build (e.g. changes in the Table of Contents format)
