docs(notebooks): add wire-cutting guide #26

Summary

This notebook contains a how-to guide on wire-cutting.

Details and comments

This is a how-to guide on wire cutting that was presented at the APAC Practitioner's Forum.
There are two known drawbacks to this -
(i) for simulation it uses cloud simulators since there are some issues with Qiskit which prevents us to use local simulator with circuit-knitting-toolbox at this moment; and
(ii) circuit-knitting-toolbox which supports Primitives V2 is not yet publicly available. So we use Primitives V1 only.
This builds on the basic example of wire cutting shown in circuit-knitting-toolbox

This notebook currently uses Primitives V1. This is because as per my last discussion with Jim Garrison, circuit-knitting-toolbox can support Primitives V2, but it should be separately installed from source for now. Support for Primitives V2 is not yet available for pip installation. So, I am sticking to Primitives V1 till the time support for V2 is available in pip installation.
This notebook still uses cloud simulators for running the smaller examples. This is because BackendSampler has some shortcomings where it cannot deal with multiple/empty classical register. This has been reported as an issue, but it is not expected to be solved before Qiskit 1.1.
