[autorevert] fix pending job check (#6982)

Pending job detection was incorrect.
- Before: `has_pending_jobs` checked `status == "pending"`, which GitHub
Actio
ns does not emit; statuses are typically `queued`, `in_progress`,
`completed`.
  - Now: Treat any job with `status != "completed"` as pending.
