AK: Fix the JsonArray constructor for accepting an iterable type

Browse source 
There were a couple of issues here. First, the IterableContainerOf
concept was testing if dereferencing an iterator of ContainerType<T>
returns a value of type T. However, it should return a T&.

Second, the constructor was trying to move values out of a constant
reference to the container. We now accept both lvalue and rvalue
containers.
