[kirkstone][PATCH 5/9] manuals: add initial sphinx-lint support

[michael.opdenacker@bootlin.com]

From: Michael Opdenacker <michael.opdenacker@bootlin.com>

Makes it possible to catch errors not reported by sphinx,
such as idle spaces. After customization, this should be used
to enforce our syntax conventions, such as two spaces after a "-"
character to introduce a list item.

Just run "make sphinx-lint".
