Feature: Add support for Groovydoc Hovers

[samrocketman]

https://marketplace.visualstudio.com/items?itemName=redhat.java supports Javadoc hovers. I extensively use Groovydoc for my project.

Example Project

You can use my open source project to help with development. It uses VSCode dev containters and is integrated with Vagrant.

• Example Groovydoc output: https://sam.gleske.net/jervis-api/
• Source Code with Groovydoc: https://github.com/samrocketman/jervis

Request

It would be nice if Groovydoc rendered similarly to Javadoc with code blocks, rich HTML, and cross-class and cross-package links.
