What happened, and what did you expect to happen?

I (inadvertently fell down the rabbit hole) in upgrading a jupyter book to v2. This is one of the two issues I ran into.

The jupyter book conversion of _toc.yml to myst.yml produced a toc with backslashes.Locally on Windowsjupyter-book start looks correct and serves without issues. But, I was getting missing TOC contents on CI. I finally realized it was because it needed unix paths 🤦

v1 toc had forwardslashes:https://github.com/TimMonko/napari-workshops/blob/5adb2b5451f2fc59d68b36a4fdf71711f66ffcba/napari-workshops/_toc.yml
what I had to do:https://github.com/TimMonko/napari-workshops/pull/5/files

My guess is the paths are just created with backslashes on Windows. But I don't know 🤷

What version of Jupyter Book are you running?

v2.0.0b*
