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

In the absence of good use cases, I'll decline the API expansion.

Feel free to post a PR to have the deque documentation to mention d[0] indexing more prominently.  Am not really sure that is needed though, we don't have to point out the same thing for lists and I haven't encountered any misunderstandings on the topic.  This would be just a minor usage note.
