SDK NullPointerException due to missing @odata.type field during select query

Describe the bug

During a select query for users, mapping them to the User class fails with following NPE

java.lang.NullPointerException: parameter node cannot be null
	at java.util.Objects.requireNonNull(Objects.java:246)
	at io.kiota.serialization.json.JsonParseNode.<init>(JsonParseNode.java:38)

	at com.microsoft.graph.groups.item.members.graphuser.GraphUserRequestBuilder.get(GraphUserRequestBuilder.java:70)

Expected behavior

The user(s) should be selected by the query, mapped and returned in a response object

How to reproduce

Code snippet to reproduce:

final String groupId = "test group id";
final GraphUserRequestBuilder request = client.groups()
                .byGroupId(groupId)
                .members()
                .graphUser()
                .get(req -> {
                    req.queryParameters.select = "id,name,mail";
                    req.queryParameters.filter = "id in (1,2,3)";
                    req.queryParameters.count = true;
                    req.headers.add("ConsistencyLevel", "eventual");
                    }
                })

Code snippet to reproduce the NPE with the JsonNode

import com.fasterxml.jackson.databind.node.JsonNodeFactory;
import com.fasterxml.jackson.databind.node.ObjectNode;
import io.kiota.serialization.json.JsonParseNode;
import io.kiota.serialization.json.JsonParseNodeFactory;

class Scratch {
    static void main() {
        try {
            var a = new JsonParseNode(new JsonParseNodeFactory(), new ObjectNode(new JsonNodeFactory(false)));
            var b = a.getChildNode("@odata.type");
        } catch (NullPointerException e) {
            System.out.println("Exception!");
        }
    }
}

Replicating this code in Graph UI returns following example response:

{
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users(id,name,mail)",
    "@odata.count": 2,
    "value": [
        {
            "id": "id 1",
            "name": "name 1",
            "mail": "mail 1"
        },
        {
            "id": "id 2",
            "name": "name 2",
            "mail": "mail 2"
        }
    ]
}

Which then leads to the NPE as the SDK is expecting @odata.type field being set here

https://github.com/microsoftgraph/msgraph-sdk-java/blob/main/src/main/java/com/microsoft/graph/generated/models/User.java

@jakarta.annotation.Nonnull
    public static User createFromDiscriminatorValue(@jakarta.annotation.Nonnull final ParseNode parseNode) {
        Objects.requireNonNull(parseNode);
        final ParseNode mappingValueNode = parseNode.getChildNode("@odata.type"); <- NPE being caused here
        if (mappingValueNode != null) {
            final String mappingValue = mappingValueNode.getStringValue();
            switch (mappingValue) {
                case "#microsoft.graph.agentUser": return new AgentUser();
            }
        }
        return new User();
    }

_No response_

### Other information

_No response_

从 src/main/java/com/microsoft/graph/generated/models/User.java 中的 User.createFromDiscriminatorValue 开始，跟踪缺失的 @odata.type 字段对应的 JsonParseNode.getChildNode。使用提供的 select 查询或 JsonNode 片段重现该问题，然后验证仅包含 id、name 和 mail 的用户能够在不发生 NullPointerException 的情况下完成映射并返回。
