index.rst is the page that becomes index.html, but currently just has
some blurb. Although this page will only be seen if viewing the docs
as built from the libcamera tree it'd be better if it were more of an
introductory page. Include the content of docs.rst to improve it. As
we're no longer including the content from README.rst the labels that
enabled that can be dropped.

With this change whether viewing the documentation as built in the
libcamera tree or on the Docs page of the website, the landing content
will be the same.

The CSS for the documentation's theme currently hides the toctree from
the generated body in html, as it's already displayed on every page via
the theme's CSS. This change reorders the page such that the CSS that
hides the toctree no longer works - update the CSS to retain the
current behaviour.
