Graphql client handle UUID
Hi, I am writing tests for my graphql endpoint like follows

Endpoint
```java
package graphql

import types.Organization;
import io.quarkus.security.Authenticated;
@GraphQLApi
public class OrganizationResource {

    @Authenticated
    @Query
    public Organization organization(@NonNull UUID id) {
        return Organization.builder().id(id).value("test").build()
    }
}
```

Graphql type
```java
package types;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;

import java.util.UUID;

@AllArgsConstructor
@Data
@Builder
@JsonIgnoreProperties(ignoreUnknown = true)
public class Organization {
    private UUID id;
    private String value;
}

```

Graphql client
```java
@GraphQlClientApi
interface Client {
  Organization organization(@NonNull @Name("id") String id);
}
```

Test
```java
public class OrganizationResourceTest {
   @Test
    public void testOrganizationQuery() {
        var id = UUID.randomUUID()
        var response = graphql.organization(organization.getId().toString());
        assertEquals(id, response.getId());
    }
}
```
but I receive this error 

```
io.smallrye.graphql.client.typesafe.api.GraphQlClientException: errors from service:
- {"message":"Validation error of type SubSelectionNotAllowed: Sub selection not allowed on leaf type String of field id @ 'organization/id'","locations":[{"line":1,"column":59}],"extensions":{"description":"Sub selection not allowed on leaf type String of field id","validationErrorType":"SubSelectionNotAllowed","queryPath":["organization","id"],"classification":"ValidationError"}}
query: query organization($id: String!) { organization(id: $id) {id {mostSigBits leastSigBits} value } }
```

It seems like the client is not mapping the UUID field to a String field which is how the graphql endpoint is returning fields of that type.

Any suggestion on how to handle this case?
