調べてみると、 dependabotが作成したPRでcommentを書くGitHub Actionsが失敗していた。depndabotの権限がread-onlyになっているせいらしい。

> In March we made a change in GitHub Actions that forced workflows triggered by Dependabot to run with a read-only token.

# 解決策

`permissions`で必要な権限を付与する

例. PRにコメントするGitHub Actionsの場合

```
permissions:
  pull-requests: write
```

詳細のpermissionsについては、[Assigning permissions to jobs](https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs)
