[docs] 404 on all https://docs.python.org/3/download.html links

[Mark Brooker]

Hi,

I just tried to download a copy of the python docs and got 404 errors for all 
formats and all packings.

Could you create a .mobi format download as well? Calibre can convert from 
epub to mobi but the result is often unsatisfactory and I prefer reading doc 
on my kindle. It's not always as convenient as a paper book but is superior in 
many ways.
