Describe the bug

Error reporting when calling RelationshipApi.createRelationship() using Java Client for Ory Keto(verison:0.11.0-alpha.0)，detail info：
Exception in thread "main" java.lang.NoSuchMethodError: okhttp3.RequestBody.create(Ljava/lang/String;Lokhttp3/MediaType;)Lokhttp3/RequestBody;

Reproducing the bug

First, I started the keto service：
1.mkdir data & cd data
2.clone https://github.com/ory/keto.git
3.download https://raw.githubusercontent.com/ory/meta/master/install.sh
4.bash install.sh -d -b . keto v0.11.1-alpha.0
5.sudo mv ./keto /usr/local/bin/
6.keto serve -c /data/keto/contrib/docs-code-samples/expand-api-display-access/keto.yml

Secondly, I use the Java Client for Ory Keto(verison:0.11.0-alpha.0) to call the keto service according to the demo in the guides
1.init a springboot project
2.import Java Client for Ory Keto(verison:0.11.0-alpha.0) in the pom.xml

sh.ory.keto
keto-client
0.11.0-alpha.0

3.Create a junit test class as follows and test it according to the example（https://github.com/ory/client-java/blob/master/docs/RelationshipApi.md#createRelationship）

private static void createRelationship() {
ApiClient defaultClient = Configuration.getDefaultApiClient();
defaultClient.setBasePath("http://localhost:4467");
RelationshipApi apiInstance = new RelationshipApi(defaultClient);
CreateRelationshipBody createRelationshipBody = new CreateRelationshipBody(); // CreateRelationshipBody |
createRelationshipBody.setNamespace("messages");
createRelationshipBody.setObject("lyl_obj");
createRelationshipBody.setRelation("lyl_relation");
createRelationshipBody.setSubjectId("lyl_sub");
SubjectSet subjectSet = new SubjectSet();
subjectSet.setNamespace("messages");
subjectSet.setObject("lyl_obj");
subjectSet.setRelation("lyl_relation");
createRelationshipBody.setSubjectSet(subjectSet);
try {
Relationship result = apiInstance.createRelationship(createRelationshipBody);
System.out.println(result);
} catch (ApiException e) {
System.err.println("Exception when calling RelationshipApi#createRelationship");
System.err.println("Status code: " + e.getCode());
System.err.println("Reason: " + e.getResponseBody());
System.err.println("Response headers: " + e.getResponseHeaders());
e.printStackTrace();
}
}

4.I found that the order of the incoming parameters is wrong when ApiClient#serialize calls RequestBody#create: the first parameter of RequestBody#create of okhttp3 is MediaType, but when ApiClient#serialize is called, the second parameter is passed in as MediaType：
ApiClient：
public RequestBody serialize(Object obj, String contentType) throws ApiException {
if (obj instanceof byte[]) {
// Binary (byte array) body parameter support.
return RequestBody.create((byte[]) obj, MediaType.parse(contentType));
} else if (obj instanceof File) {
// File body parameter support.
return RequestBody.create((File) obj, MediaType.parse(contentType));
} else if ("text/plain".equals(contentType) && obj instanceof String) {
return RequestBody.create((String) obj, MediaType.parse(contentType));
} else if (isJsonMime(contentType)) {
String content;
if (obj != null) {
content = JSON.serialize(obj);
} else {
content = null;
}
return RequestBody.create(content, MediaType.parse(contentType));
} else if (obj instanceof String) {
return RequestBody.create((String) obj, MediaType.parse(contentType));
} else {
throw new ApiException("Content type "" + contentType + "" is not supported");
}
}

okhttp3：
public static RequestBody create(@Nullable MediaType contentType, String content) {
Charset charset = StandardCharsets.UTF_8;
if (contentType != null) {
charset = contentType.charset();
if (charset == null) {
charset = StandardCharsets.UTF_8;
contentType = MediaType.parse(contentType + "; charset=utf-8");
}
}

    byte[] bytes = content.getBytes(charset);
    return create(contentType, bytes);
}

Additional Context

No response

Start with sh.ory.ApiClient.serialize, then trace the call from RelationshipApi.createRelationship using the Java client example in docs/RelationshipApi.md. Reproduce the NoSuchMethodError with the reported Ory Keto and client versions, and verify that the relationship creation call completes without the okhttp3 method error.
