Open the DingTalk link in browser

https://developers.dingtalk.com/document/app/message-link-description

To open the link in browser, we should use this URL: "dingtalk://dingtalkclient/page/link?pc_slide=false&url=" + url.QueryEscape(singleURL)

Otherwise the page is displayed inside DingTalk client, it makes users very difficult to visit non-public URLs in DingTalk webhook messages.

The patch is tested and it works as expected.

@wxiaoguang please update the test code.
