refactor(global-shortcut): enhance un/register to accept an array, remove un/registerAll

[amrbashir]

closes #1101

[lucasfernog]

Should we do the same on the Rust side?

enum ShortcutArg {
  Single(T),
  List(Vec<T>),
}

impl From<T> for ShortcutArg { .. }
impl From<Vec<T>> for ShortcutArg { .. }

pub fn register(&self, shortcut: impl Into<ShortcutArg>) {...}

Also should it unregister all registered shortcuts if the list is empty (or we provide a separate API for that)?

I don't think we should do the same on Rust, it is better to be kept as is.

Also should it unregister all registered shortcuts if the list is empty (or we provide a separate API for that)?

we could bring back unregisterAll I guess
