Colleen Murphy ba9c1a3bec Fix docs builds
With the new way of generating docs in the gate[1] our autodoc builds
are slightly broken. Put the required dependencies for doc building and
autodoc generation into doc/requirements.txt. We can also now remove
docs-related requirements from test-requirements.txt.
