Deps in //docs/website.

www.chromium.org will be switching from being hosted on Classic
Google Sites to a "static website" system where all the content
is hosted in a Git repo (and most of it is written in Markdown).

If you want to make edits to the website, I expect most people
will use the UI to edit a single page, but there's currently no
preview functionality for those edits prior to uploading a CL.
Also, there's no good way to add other assets (like images) in
that UI, or to edit multiple files at once.

To address those things, you can check out the website locally
with `fetch website`, but it may be convenient to just have a copy
already in your Chromium checkout (the repo is small). Plus,
this is (hopefully) the easiest path to getting website pages
to show up in codesearch.

So, this change adds a DEPS entry to pull the repo into
//docs/website.
