Response header does not reflect the correct version for HTTP2 requests

Issue

The response header does not reflect the correct version for HTTP2 requests. Even though, wiremock replies in h2 but the version in the response header shows "HTTP/1.1 200". This is caused by the hardcoded value in the toString() method of Response.java class

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        **sb.append("HTTP/1.1 ")**.append(status).append("\n");
        sb.append(headers).append("\n");
        // no longer printing body
        return sb.toString();
    }

Environment

• Which version of WireMock you're using -
  2.31.0 standalone

• How you're starting and configuring WireMock, including configuration or CLI the command line
  Starting wiremock in standalone mode inside a docker container

Steps to reproduce

1. Insert some request-response data in wiremock
2. Try to make a request with h2
3. See the response on the console. You get the response like below for the h2 requests

Response:
HTTP/1.1 200
Content-Type: [application/json]
Matched-Stub-Id: [fc793a71-3651-4c9b-bafd-9678c6265950]

Is this fixed in 2.32.0? I tried and below is the reponse

curl --http2 -s -I -X GET http://localhost:8080/api/test

HTTP/1.1 101 Switching Protocols

HTTP/2 200
