Creating a Team always returns an empty Team : Cannot get the ID of the created Team.

Describe the bug

Hello,

I'm using com.microsoft.graph:microsoft-graph:6.21.0 right now.

I'm trying to create a new team and then to get the ID, and the Operation ID of the result.

Team result = getGraphClient().teams().post(team);

The returned Team is always null as the JSON returned by the API is always empty. It seems that those informations are returned in the response header but I cannot access to it as the response is just a Team object.
In v5, it was returned in the object.

How am I supposed to retrieve the ID and the Operation ID of a newly created Team ?

Expected behavior

I expected that the returned Team object will contain the ID and the Operation as it was the case in the v5 of this library.

How to reproduce

Create a team with the code :

Team result = getGraphClient().teams().post(team);

The result will always be a null object.

SDK Version

6.21.0

Latest version known to work for scenario above?

5.x

### Configuration

_No response_

### Other information

_No response_

Start with the teams().post(team) call in the Java SDK and compare its behavior in version 6.21.0 with the reported 5.x behavior. Inspect how the create response exposes the Team ID and operation ID, then verify that the result is no longer null and both values are accessible.
