docs: stable-kernel-rules: improve structure and a few tweaks

When adding something to this document earlier I noticed that readers need to perform some back and forth to fully understand things; I also noticed a few other aspects that seemed somewhat odd for me with my background on writing and editing texts.

Find attached a few patches to improve things. The first three are mainly moving text around to a structure which is somewhat clearer. They leave quite a few rough edges behind that are fixed in in the last patch of the series, which changes a few other changes as well; thx to the prep patches the diff should be relative straight-forward to understand.

These patches are on-top of the following series that currently is in the driver-core-testing branch:

Ciao, Thorsten

v1:
* new patch-set based on patch 3/3 and other feedback to the following patchset[1], but slit off into a seperate set with four distinct patches to make it easier to see what is actually changed

* append one more patch for something that came up
