ChangeNotificationCollection not included

Describe the bug

ChangeNotificationCollection and ChangeNotification are not included in the SDK for python, but are for c# (see c#-example here: https://github.com/microsoftgraph/msgraph-training-changenotifications/blob/ca2b76fb295018595298f85c49e23f8fad96b1c8/demos/03-track-changes/Controllers/NotificationsController.cs#L76C56-L85).

Expected behavior

Import of

from msgraph.generated.models.changenotificationcollection import ChangeNotificationCollection 
from msgraph.generated.models.changenotification import ChangeNotification 

grants use of the classes.

How to reproduce

install the latest version of the sdk
try to import the missing classes

首先，在最新的 Python SDK 中复现 ChangeNotificationCollection 和 ChangeNotification 的导入，然后将可用的生成模型与 issue 中链接的 C# 示例进行比较。当两个导入都能正常工作，并且可以按描述使用这些类时，即视为完成。
