PATCH /subscriptions/{id} shouldn't require both properties

Describe the bug

As per the documentation, PATCH https://graph.microsoft.com/beta/subscriptions/{id} requires only 1 property to be defined. Unfortunately, as confirmed by this customer, the Java SDK requires both properties to be specified or the request fails with this error message:

Subscription must contain either the 'expirationDateTime' or 'notificationUrl' property and its value.

More details on the bug as reported by the customer @Yusvanth are in Microsoft Graph Q&A

The feature engineers have confirmed that this issue doesn't occur on the REST API or other SDKs.

Please assist to resolve the bug.

Expected behavior

Only the expirationDateTime property is required.

Comece rastreando o tratamento de PATCH /subscriptions/{id} no Java SDK, usando a documentação vinculada do Microsoft Graph e o issue do cliente como contexto de reprodução. Verifique se uma solicitação contendo apenas expirationDateTime é aceita e confirme que a validação existente ou o comportamento da solicitação não exige mais notificationUrl.
