Add a doctor command to fix inconsistent run status (#35840) (#35845)

Backport #35840

#35783 fixes an actions rerun bug. Due to this bug, some runs may be
incorrectly marked as `StatusWaiting` even though all the jobs are in
done status. These runs cannot be run or cancelled. This PR adds a new
doctor command to fix the inconsistent run status.

```
gitea doctor check --run fix-actions-unfinished-run-status --fix
```
