[v9_16] Regenerate man pages with docutils 0.17.1
The Debian 10 (buster) Docker image, which GitLab CI uses for building documentation, currently contains the following package versions:
- Sphinx 4.2.0
- sphinx-rtd-theme 1.0.0
- docutils 0.17.1
Regenerate the man pages to match contents produced in a Sphinx environment using the above package versions. This is necessary to prevent the "docs" GitLab CI job from failing.
