Remove "fix" of "deques" - it is quite legit

Kudos to @psobolewskiPhD for a sharp eye and explanation.  "deques" is a legit
form of a "deque" which is a data structure ("Double-Ended Queue") which is
used/accepted in many languages, Python included.  Thus we can expect to
encounter it often and "fixing" it to mean "dequeues" (3rd form of "dequeue" as
"remove from queue"?) is totally incorrect.

Plural form is "deques", as also described on
