Export Harmonica's Documentation as single pdf

[MGomezN]

Hello!

Harmonica has a beautiful documentation website. However, I'm reading the documentation to learn, so I would like to make annotations, highlights, identify typos, etc., to improve the documentation. This task would be easier if I could have all the documentation as a single pdf. The current option allows downloading individual sections as pdf.
I have read about how to implement what I want: build an HTML output and then use Sphinx to convert it to pdf. Is that the best way to do it?
