Fix missing about content in refstack-ui

Refstack webpage's about section is not rendered correctly. The bug is
tracked in here:
https://tree.taiga.io/project/openstack-interop-working-group/issue/81

This patch will update documentation build process to generate html
files by changing paths to html files in about.html.

Replace deprecated options in doc/source/conf.py by the new ones:
* openstackdocs_bug_project
* openstackdocs_bug_tag
