[Schema Inaccuracy] `issue.state_reason` missing enum variant: `duplicate`

まず、issue に示されている issue.state_reason の OpenAPI スキーマ定義を見つけ、次に提供された curl コマンドを使用して、API が現在 duplicate を返すことを確認します。enum に既存のバリアントと並んで duplicate が一覧表示され、そのレスポンスをスキーマが正確に記述していれば完了です。

(this issue was reposted from https://github.com/orgs/community/discussions/150535, cc https://github.com/yanyongyu/githubkit/issues/188)

Current definition:

      "state_reason": {
        "description": "The reason for the current state",
        "type": [
          "string",
          "null"
        ],
        "enum": [
          "completed",
          "reopened",
          "not_planned",
          null
        ],
        "examples": [
          "not_planned"
        ]
      },

Expected

duplicate listed among variants. Here's an issue with that state_reason (https://api.github.com/repos/python/mypy/issues/18584):
