docs website: Wordsmith homepage

Wordsmith the docs project website title heading to make it clearer
that this is the docs project portal and not the main website home.
Also, tighten redundant uses of "FreeBSD". Saying it at least once
in every line and heading is quite tedious. Similarily, give the
anchors a more accurate and unique name to ease contribution.

Also tidy grammar on the search bar. Search bars never get punctuation,
unless it's an elipsis, the project uses serial commas, and "in" is not
really correct here.
