repurpose 5.6.x branch to provide local docs build

* remove unused workflows, scripts, and configuration (now handled by docs-build branch)
* upgrade Antora to 3.1 (and Node.js to 16)
* tune playbook settings
* reconfigure docs build for local build only
* add patch to support using linked worktree as Antora content source
* remove Antora extensions not needed for local builds
