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

Comienza con el modelo graph.models.Channel y compáralo con el Microsoft Graph channels endpoint mostrado en el issue. Añade compatibilidad para leer y aplicar parches a layoutType, incluidos los dos valores permitidos, y verifica después que el SDK exponga la propiedad sin usar additionalData.
