picked
Optional flag indicating if this item is picked initially. This is only honored when using the window.showQuickPick API. To do the same thing with the createQuickPick() API, simply set the QuickPick.selectedItems to the items you want picked initially. (Note: This is only honored when the picker allows multiple selections.)
