Fix docs reqs for new pip
Per [1], the docs requirements were failing (or at least could) due to
test-requirements being used instead of doc/requirements. The former
may include dep versions not compatible with the upper-constraints and
hence cause issues for the new pip resolver. This patch fixes that.
