Now that a new styling for API references was added with commit 934f45c,
we can remove the extra CSS that was crafted specifically for JavaScript
API references with commit 05a0a49a. While we're at it, this commit also
applies the new styling to definition lists that were missing it, like
it was done for the page on views with commit 120ae785.

The terminology did not really make sense for a lot of these sub pages.
This change should have been done long ago, but was probably delayed
because some people in Odoo call the web client the "backend", which is
really misleading.
This commit also renames the title "Reference Guides" to "Reference",
since this section does not contain any guides anyway.
