All-digit keys of a response body have the wrong path in the matching rules of the generated pact file

[mrickly]

Tested with au.com.dius.pact.core:model:4.6.11

Change leading to the problem (it seems): 2dd6271#diff-80e566076d12e545a06e091b743fc936113a142ad0ab0572c6053c136c8a4703R211

Java Code:

    private DslPart createOzoDatenResponsePayload(final String vrsvereinbarungsnummer) {
        return newJsonBody(mapEntry -> mapEntry.object(vrsvereinbarungsnummer, wrapperDto -> {
            wrapperDto.eachLike(OzoDatenAdapterDto.Fields.VRS_GEGENSTAENDE, vrsGegenstaende -> {
                vrsGegenstaende.stringType("@class", "EventDto");
            });
        })).build();
    }

Result:

        "matchingRules": {
          "body": {
            "$[660202434058].vrsGegenstaende": {
              "combine": "AND",
              "matchers": [
                {
                  "match": "type"
                }
              ]
            },
            "$[660202434058].vrsGegenstaende[*].@class": {
              "combine": "AND",
              "matchers": [
                {
                  "match": "type"
                }
              ]
            }
          }
