Allow opening Javadoc in browser

I often want to view the Javadoc in the browser for easier reading, or to read package/module documentation (which afaik isn't easily viewable somehow inside VS Code).

Environment

• Operating System: Windows 10
• JDK version: 13.0.1
• Visual Studio Code version: 1.41.1
• Java extension version: 0.55.1

Steps To Reproduce

option 1:

1. hover over an element

option 2:

1. trigger autocompletion for an elemention

Current Result

option 1:

option 2:

Expected Result

I'd like for the pop-up dialogs to have an icon which opens the Javadoc of the element in the default browser. I'd already be very happy if this would work for just JDK classes, but ideally this would also work for Maven dependencies.

Usa los popups de documentación de hover y completion descritos en la reproducción como puntos de entrada. Comprueba cómo se resuelve Javadoc para las clases de JDK y las dependencias de Maven; se considera terminado cuando ambos popups ofrecen una acción del navegador que abre la Javadoc relevante, y es aceptable admitir solo JDK si no está disponible la compatibilidad con dependencias.
