Rework knowledgebase sync; add kb-publish for GitLab Pages

- Rename sync-knowledgebases to kb-sync (drop the aliased indirection)
- Generalize source discovery: scan each ~/work project for either
  docs/knowledgebase or documentation/knowledgebase
- Add kb-publish: rsync collected docs into the site repo, build the
  MkDocs site, and commit/push to publish to GitLab Pages
