Provide diataxis framework as an ebook

[chendrix]

I'd love to read it on my kindle and share it as an ebook with my colleagues!

Maybe as easy as to add additional builds (PDF, ebook) through readthedocs: https://docs.readthedocs.io/en/stable/downloadable-documentation.html

Which should be available for download (if built) under: https://readthedocs.org/projects/documentation-system/downloads/
