That's a super hacky epub that I just generated from the markdown source and have not read over thoroughly. Formatting is a bit different, and code blocks have no labels, which are occasionally significant... but from a quick glance it looks pretty close.
Also https://janet.guide/all has the full text of the book, which you could save to HTML and convert to an epub with pandoc (or print to a PDF). Not sure if the results would be better or worse.
