Gio.PropertyAction.new
function new(name: String, object: void, property_name: String): Gio.PropertyAction {
    // Gjs wrapper for g_property_action_new()
}
  Creates a Gio.Action corresponding to the value of property property_name on object.
The property must be existent and readable and writable (and not construct-only).
This function takes a reference on object and doesn't release it until the action is destroyed.
