[docs] [issue35118] Add peek() or first() method in queue

[Windson Yang]

New submission from Windson Yang <wiwindson at gmail.com>:

I found other languages like Java and C++ have the method to access the first value in Queue like first() and peek(). Since we use deque_ to create Queue now, it's easy to implement in python using the index. Otherwise, we can add this to the document? I also found some discussion_ here.
