gnu: python-sphinx-prompt: Fix tests.

docutils>=0.19 broke the tests, which upstream fixed in a newer
commit. Cherry-pick it.

* gnu/packages/patches/python-sphinx-prompt-docutils-0.19.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register it.
* gnu/packages/sphinx.scm (python-sphinx-prompt)[origin]: Use it.
