docs: Redirect all technical doc pages.

We publish the two pages that were being published under here to the new
edx-platform docs under docs.openedx.org so update this doc site to
redirect to that site for all pages.

Once this version has been published, we should be safe to remove this
doc project from the platform and all future changes should go through
the single edx-platform docs site.
