docs: kernel-docs: order reference from newest to oldest

The documents on each section of this document are ordered by its
published date, from the newest to the oldest.

In the kernel-docs.rst, the references on each section of this document
are intended to be ordered by its published date, from the newest to the
oldest. The Linux Kernel Module Programming Guide was published in 2021;
so, it is placed at the top as the most recent publication after the
rolling-version "Linux Kernel Mailing List Glossary" reference.
