Missing Enumeration Members

Describe the bug

Deserializing the JSON response from the getManagedDevice API endpoint (no issue here) and then casting it into a ManagedDevice object throws an exception.

The JSON response returned from the API includes:

"managementAgent": "intuneAosp"
"deviceEnrollmentType": "androidAOSPUserOwnedDeviceEnrollment"

Neither of these values have a member in the associated enumerations contained in the ManagedDevice class:
• ManagementAgentType enumeration does not have an intuneAosp member
• DeviceEnrollmentType enumeration does not have an androidAOSPUserOwnedDeviceEnrollment member

Casting the deserialized response from the getManagedDevice API results in the following exception:

Newtonsoft.Json.JsonSerializationException: Error converting value "intuneAosp" to type 'System.Nullable`1[Microsoft.Graph.ManagementAgentType]'. Path '[1].managementAgent'.
---> System.ArgumentException: Requested value 'intuneAosp' was not found.

Expected behavior

Ability to deserialize the JSON response from getManagedDevice API endpoint and cast it into a ManagedDevice object

How to reproduce

1. Enroll a DigiLens (Set up Intune enrollment for Android (AOSP) corporate-owned user-associated devices)

2. Call the getManagedDevice API

3. Review the JSON (API returns success and a valid JSON response)
   "managementAgent": "intuneAosp"
"deviceEnrollmentType": "androidAOSPUserOwnedDeviceEnrollment"

4. Deserializing the JSON response and casting it into a ManagedDevice object results in the exception

### Other information

• [ManagementAgentType enumeration](https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/c75439214c6752d0dff406ab4b0905a4369a7b5d/src/Microsoft.Graph/Generated/Models/ManagementAgentType.cs) requires an `intuneAosp` member
• [DeviceEnrollmentType enumeration](https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/c75439214c6752d0dff406ab4b0905a4369a7b5d/src/Microsoft.Graph/Generated/Models/DeviceEnrollmentType.cs) requires an `androidAOSPUserOwnedDeviceEnrollment` member

Start with src/Microsoft.Graph/Generated/Models/ManagementAgentType.cs and DeviceEnrollmentType.cs, then review how those enums are used by ManagedDevice.cs. Verify the reported JSON values against the enum definitions and check the existing serialization behavior. Done means both values deserialize into ManagedDevice without the reported exception.
