Use CodeAction over command

[mjbvz]

Switch the code action provider to use CodeActions instead of commands. CodeActions work better with VS Code's Refactor commands. They also let us avoid an extra command invocation

@mjbvz While the vetur.applyWorkspaceEdits was refactored to be a pure code action with edit, the vetur.chooseTypeScriptRefactoring is still implemented in the extension so doesn't work in other editors.

Can you say something about that? Is there a reason you couldn't refactor that also?

I understand that for performance reasons you might want to delay computations and thus use the command but I'm not quite sure I understand why it can't be a pure server command instead.

I will study this question when I refactor #1495.
I will try to use a pure server command instead.
