[PATCH b4 08/21] docs: maintainer: use deprecated admonition

[Quentin Schulz <foss+kernel@0leil.net>]

From: Quentin Schulz <quentin.schulz@cherry.de>

Use the rST deprecated admonition[1] to specify since which release this
has been deprecated.

One can add information as to what to replace the option with, so that's
what's done wherever we have that information.

The version is the first one to have the commits which inserts the
deprecated string for the options, which is commit 2ce1e619ddb4 ("docs:
complete most of the maintainer docs") available in v0.10.
