Channel layoutType property is missing in the SDK

Describe the bug

The property layoutType is missing for the graph.models.Channel-Object. Without it reading the actual value of a channel is hard. Patching the property can be done with some workarounds using additionalData (see below).

The object:

A graph request:
https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}

Expected behavior

The property should be present in the graph.models.Channel-Object. Also an enum for the two allowed values would be nice.

How to reproduce

Simply use some sdk version and try to read or patch the layoutType of a channel.

SDK Version

6.63

Latest version known to work for scenario above?

none I guess

Known Workarounds

For a patch you can use one of:

.getAdditionalData().put("layoutType", "post");
.getAdditionalData().put("layoutType", "chat");

I don't know if there is a workaround for reading.

Debug output

No response

Configuration

This should not impact the issue, since it is not present in the models of the java-SDK.

Other information

No response

Start with the graph.models.Channel model and compare it with the Microsoft Graph channels endpoint shown in the issue. Add support for reading and patching layoutType, including the two allowed values, then verify that the SDK exposes the property without using additionalData.
