Improve hover code actions UX

[husanjun]

1. If only one, If the action link is clicked, it is ran immediately, circumventing the quick panel.
   

2. If only diagnostics, don't show navigation
   

3. Improved hover phantom problem

BTW, When hovering, the code action does not just occur during the diagnosis

That code action title can look like just some random text there, depending on what it says, I feel.
Maybe we should prefix it with Code action:?

Yes.
Lets discuss this first before doing any changes but something like that, yes. Ideally with a space after the colon :)
