[dpdk-dev] [PATCH] doc: fix minor sphinx build warning

[John McNamara <john.mcnamara@intel.com>]

Fix for a minor Sphinx build warning in the ABI guidelines docs:

    versioning.rst:126: WARNING: Bullet list ends without a
                        blank line; unexpected unindent.

Also added a RST label to the start of the doc to allow it
to be linked to from other docs.
