[BUG] match_only_text does not return analyzer and search_analyzer

What is the bug?

GetMappingRequest does not return analyzer and search_analyzer for type match_only_text

How can one reproduce the bug?

OpenSearchClient client = //TODO init

client.generic().execute(Requests.builder()
        .endpoint("struthio-camelus")
        .method("PUT")
        .body(Body.from("""
                {
                  "settings": {
                    "index": {
                      "number_of_shards": 1,
                      "number_of_replicas": 0
                    }
                  },
                  "mappings": {
                    "properties": {
                      "egg-color": {
                        "type": "text",
                        "analyzer": "standard",
                        "search_analyzer": "whitespace"
                      },
                      "feather-color": {
                        "type": "match_only_text",
                        "analyzer": "standard",
                        "search_analyzer": "whitespace"
                      }
                    }
                  }
                }
                """.getBytes(StandardCharsets.UTF_8), "application/json"))
        .build());


GetMappingRequest request = GetMappingRequest.builder()
        .index("struthio-camelus")
        .build();

GetMappingResponse response = client.indices().getMapping(request);
System.out.println(response.toJsonString());

What is the expected behavior?

egg-color and feather-color should both return both analyzers, but only the egg-color returns both

match_only_text should have the parameters according to the documentation

An http call on the index also returns both analyzers on the match_only_text field

What is your host/environment?

Docker OS 3.7.0 , java client 3.9.0

Do you have any screenshots?

Output of System.out:

{
  "struthio-camelus": {
    "mappings": {
      "properties": {
        "egg-color": {
          "type": "text",
          "analyzer": "standard",
          "search_analyzer": "whitespace"
        },
        "feather-color": {
          "type": "match_only_text"
        }
      }
    }
  }
}

Start with the GetMappingRequest and GetMappingResponse entry points and reproduce the mapping shown in the issue against OpenSearch 3.7.0. Compare the Java client's response with the HTTP mapping response, then verify that match_only_text preserves analyzer and search_analyzer like text does.
