デフォルトでは、`.openapi()` メソッドはプロパティ `.openapi_schema` に内容があるかを確認し、あればそれを返します。

なければ、`fastapi.openapi.utils.get_openapi` にあるユーティリティ関数を使って生成します。

この関数 `get_openapi()` は次の引数を受け取ります:

- `title`: ドキュメントに表示される OpenAPI のタイトル。
- `version`: API のバージョン。例: `2.5.0`。
- `openapi_version`: 使用する OpenAPI 仕様のバージョン。デフォルトは最新の `3.1.0`。
- `summary`: API の短い概要。
- `description`: API の説明。Markdown を含めることができ、ドキュメントに表示されます。
