ManagedDevices list request: filter by deviceType do not work. And also a wrong deviceType is returned in the response.

Describe the bug

As mentioned in docs https://learn.microsoft.com/en-us/graph/api/resources/intune-devices-manageddevice?view=graph-rest-beta , ManagedDevice.DeviceType field reflects actual device type and supports filtering.

But it has two problems:

• deviceType field has a wrong value from the LIST request. It shows 'windowsRT' for the cloudPC devices.
• filtering by this field do not work. it return all devices ignoring provided filter.

This bug reproduces on Dotnet SDK and in Graph Explorer.
But it is not reproduced on the Intune portal. It works correct here

Expected behavior

• Correct deviceType should be returned from the list devices request
• Filter by deviceType should work

How to reproduce

My request:
https://graph.microsoft.com/beta/deviceManagement/managedDevices?$select=model,deviceType&$filter=deviceType eq 'cloudPC'

Graph response:
[
{
"model": "",
"deviceType": "unknown" // problem: this device should be filtered out
},
{
"model": "Virtual Machine",
"deviceType": "windowsRT" // problem: this device should be filtered out
},
{
"model": "Cloud PC Frontline 2vCPU/4GB/64GB",
"deviceType": "windowsRT" // wrong: it is cloudPC
},
...
]

### Configuration

_No response_

### Other information

_No response_

Start with the Graph Explorer request for /beta/deviceManagement/managedDevices using $select=model,deviceType and $filter=deviceType eq 'cloudPC', then compare its response with the Intune portal behavior. Check whether the same result occurs through the .NET SDK version 6.2.0. Done means cloudPC devices return deviceType 'cloudPC' and nonmatching devices are excluded by the filter.
