node.js v22向けにテストコードを修正

[KotaNakatsuji]

GHAの実行ランタイムをnode.js v22にしたところ、2件NGがでるようになったため修正。

結論
JSON.parseのエラーメッセージは Node.js v20 から変更された模様。
Node.js v18までは "Unexpected token o in JSON at position 1" という形式だったが、Node.js v20以降では "Unexpected token 'o', "foo" is not valid JSON" という形式に変更されている。
この変更により、Node.js v20以降でNode-REDのテストが失敗するようになったため、テストを修正して "Unexpected token" で始まることを確認するように変更。

Node.js v18: "Unexpected token o in JSON at position 1"
Node.js v20: "Unexpected token 'o', "foo" is not valid JSON"
Node.js v21: "Unexpected token 'o', "foo" is not valid JSON"
Node.js v22: "Unexpected token 'o', "foo" is not valid JSON"
