Pass the function signature in the detail property of the completion item instead of the label

Based on the gif in the README and the snapshots in https://github.com/Microsoft/vscode/issues/29126#issuecomment-432262123, it looks like this extension is appending the function signature to the function name in the label of the completion item.

This makes the reading of the items hard, especially when the docs are expanded to the side (Hit Ctrl+Space to show/hide the docs once the suggest widget is open)

The CompletionItem has a property called detail. Most extensions use this property to pass the signature. Below is a typsescript example:

I understand the temptation to include the signature as part of the label. It allows the user to choose the right item from the list at a glance. But this is only possible when the function name is small and docs are collapsed. Else, it just adds noise

Bắt đầu bằng cách truy vết nơi extension này tạo các đối tượng VS Code CompletionItem, sử dụng CompletionItem API documentation và completion UI được hiển thị trong issue. Chuyển function signature từ item label sang detail property của nó, sau đó xác minh bằng Ctrl+Space rằng các label rõ ràng hơn trong khi signature vẫn hiển thị trong phần documentation được mở rộng.
