[PATCH 2/2] docs: sort files lists in generator scripts

[luca.boccassi@gmail.com]

From: Luca Boccassi <bluca@debian.org>

In order to build the documentation in a reproducible manner, sort the lists of
files used as input, since walking the filesystem is not guaranteed to be done
in a stable order.
When converting the scripts from shell to python, sorting the input was lost.

Fixes: 53bb9a073f4f ("doc: rewrite shell scripts in Python")
