ci(docs[workflow_dispatch]) Always publish on manual trigger

why: workflow_dispatch has no push diff so dorny/paths-filter sees
no changed files, leaving PUBLISH unset and all build steps skipped.
what:
- Add github.event_name == 'workflow_dispatch' to Should publish
  condition so manual runs always build and deploy docs
