    Stop building docs with (test-)requirements.txt

    Change Iba797243d2a137b551223165a1af1a8676bcea02 was a bit
    overzealous in using {[testenv]deps} and changed the docs
    tox target to also install requirements.txt and
    test-requirements.txt which means for docs builds we're
    installing things like psycopg2 which we shouldn't be doing
    if we don't have the correct native packages installed to
    build those types of dependencies.
