[BUG] Can not send message to Baidu PNS server.

[yunbozhang-msft]

Describe the bug
We are using 21v Azure China, and use Notification hub to push messages to Baidu PNS.
Now, we can use following code to push messages to Baidu PNS, and Android devices can received notifications:

        BaiduNotification messageType1 = new BaiduNotification("{\"title\":\"test title\", \"description\":\"test description\"}");
        Notification messageType2 = Notification.createBaiduNotification("{\"title\":\"test title\", \"description\":\"test description\"}");

But actually, we want to use template send, as we need to both support to push notifications to APNS.
So I write the following codes:

        Map<String, String> prop =  new HashMap<String, String>();
        prop.put("title", "测试2023");
        prop.put("description", "测试描述2023");
        Notification messageType3 = Notification.createTemplateNotification(prop);
        
        NotificationOutcome outcome = hub.sendNotification(messageType3);

But refer to my testing, can not use template to send messages to Baidu PNS.
