doc/start: remove L and N release-related tables

This PR removes the tables for Luminous and Nautilus,
in order to keep the documentation as current as possible.
This is one a series of PRs intended to update the OS
Recommendations page. The scope of this PR is confined to
the removal of these two tables. Other PRs will update the
information elsewhere on the OS Recommendations page.
