[Feature Request] Add /// Markdown JavaDoc hovers

[qwertycxz]

Hi there.

It seems there is no Markdown JavaDoc hovers in current vscode-java?

Could this be implemented? Or how do I enable it?

Thank you.

The hover works fine in my eclipse.

Never mind. Caused by my broken org.eclipse.jdt.core.compiler setting.
