Change wire repr

[austingmhuang]

Context:
To accommodate the implementation of qml.registers, the _repr_ of Wires should be something more copy-paste friendly rather than what it is currently

Description of the Change:
The _repr_ of Wires is now Wires([0]) rather than <Wires = [0]>

Benefits:
Easier to copy and paste

Possible Drawbacks:
Might make docs confusing in other places. Not sure where else <Wires = ...> notation will be found in docs.

It's ready! It's a very small PR that just addresses the changes that come about with changing the __repr__ of Wires, notably in the docs and in other tests.
