Server generation on path level specification not rendering in final document

[pheeblyboos]

Describe the bug
As per OpenApi V3 it should be possible to override the server attribute for specific paths. See here. However when I try to append a Servers list to my OpenApiPathItem object. It does not get rendered in the final document. The fact that the OpenApiPathItem has a servers property strongly suggests that it is supported, but as far as I could see in the code base there is no implementation (I did have AI search the codebase so not 100% sure)? This is misleading at least. It is a bit of an edge case, but sometimes a necessary evil.
To be clear, it does generate a valid openapi spec, it's just missing the server attribute on the path.

OpenApi File To Reproduce
Example:
OpenApi File:

   "/runtime/webhooks/durabletask/instances/{instanceId}": {
      "get": {
        "tags": [
          "orchestration"
        ],
        "summary": "Get orchestration instance status. Auto generated endpoint by Durable Function.",
        "description": "Retrieves the status of a specific orchestration instance by ID.",
        "operationId": "getOrchestrationInstanceStatus",
        "produces": [
          "application/json"
        ],
        "parameters": [
         ... // shortened due to irrelevance
        ],
        "responses": {
... // shortened due to irrelevance
      }
    }
  }

Expected behavior
When listing a server for a path, it should be generated in the final openApiSpec as described in the openapi v3 specification.

    {
        var pathItem = new OpenApiPathItem()
        {
            Servers = new List<OpenApiServer>
            {
                new OpenApiServer
                {
                    Url = $"{req.Scheme}://{req.Host}/",
                    Description = "The server hosting the Durable Functions API."
                }
            },
        };
        
        var getOperation = new OpenApiOperation
        {
         // implementation of a path
        }
     return pathItem;
}
    public void Apply(IHttpRequestDataObject req, OpenApiDocument document)
    {
        document.Paths.Add("/runtime/webhooks/durabletask/instances/{instanceId}", StatusEndpoint(req, document));
    }

Hi @pheeblyboos
Thank you for using the SDK and for reaching out.

The fact that the snippet you shared contains a "produces" section would indicate that you're serializing the document as V2, not 3 or 3.1. And V2 path items DO NOT provide the ability to override the servers

However, while investigating this issue, I noticed we were missing some unit tests in the code base, and put together #2464 to prevent any further regression.

Let us know if you have any additional comments or questions.
