docs/config-themes: clarify and link to JavaScript plugin dev

I found it very difficult to figure out why etc/GerritSite.css wasn't
making any style modifications on non-login pages. I overlooked the fact
that this section only applies to login screens. Clarifying that section
and linking to the JavaScript Plugin Development and API document from
this Themes document would help a lot.
