Defining top-level permissions with only pull-requests: read removes the default contents: read scope from the GITHUB_TOKEN, which actions/checkout@v3 relies on to fetch the repository; as written, this workflow is likely to fail at the checkout step. Please either add contents: read (and any other required scopes) under permissions or drop the explicit permissions block here and in similar workflows so checkout can succeed.
