feat! drop support for bibliographies in document metadata

We don't use the bibliographies for anything so there's not point in
allowing users to specify it. If and when we add support for
bibliographies again, we may well want to do it in a different way.

Alas, we also have to disable reference.md because the release it
refers to uses bibliographies. We'll have to re-enable it again after
the next release.
