Switch to the new JSON writer in beanbag-docutils 2.2.
Review Request #13106 — Created June 13, 2023 and submitted
This updates our docs and release notes to use beanbag-docutils 2.2, and
to generate our JSON builds using our enhanced JSON writer and metadata
extensions, which provide more optimized builds for our website and
better SEO/social media integration.
Along with this update, there's a fix to explicitly run
reviewboard/manage.pywith Python 3, which helps with automating doc
building in a mixed Python version environment.
Successfully built the manual and release notes with the new JSON writer.
