[PATCH] docs: pdfdocs: Add space for chapter counts >= 100 in TOC

From: Akira Yokosawa
Date: Wed May 11 2022 - 22:54:23 EST


It turns out that networking.pdf has exceeded 100 chapters and
titles of chapters >= 100 collide with their counts in its table
of contents (TOC).

Increase relevant params by 0.6em in the preamble to avoid such
ugly collisions.

While at it, fix a typo in comment (subsection).
