String parameters enclosed in quotes in activity functions

We are experiencing the issue described in azure-functions-durable-extension/issues/2674 in Java activity functions.

Our existing durable function orchestration started failing out of the blue. No changes were made to the code base or dependencies of our service using durable Java functions. The service works (for now) on a linux app service plan in Azure but fails on Windows with the latest Core Tools. String parameters are enclosed in quotes in any activity functions. Using the example capitalize cities workflow from the official docs demonstrates the issue. Output below:

{
    "name": "Cities",
    "instanceId": "47f91af6-e5f0-4ea1-a363-f6d00ca812c2",
    "runtimeStatus": "Completed",
    "input": null,
    "customStatus": "",
    "output": "\"TOKYO\", \"LONDON\", \"SEATTLE\", \"AUSTIN\"",
    "createdTime": "2024-03-07T17:16:49Z",
    "lastUpdatedTime": "2024-03-07T17:16:51Z"
}

从 endtoendtests/src/main/java/com/functions/AzureFunctions.java 开始，使用最新的 Core Tools 在 Windows 上复现 capitalize cities 工作流。将 activity 输出与链接的 azure-functions-durable-extension issue 进行比较；当字符串参数不再带有包围引号返回时，即表示完成。
