Describe the fix or the content request.

In the section, where the experimental_min_eigenvalue_ref is calculated, we should be using the ref_result.x and the ref_ansatz instead of result.x and raw_ansatz:
That is:

experimental_min_eigenvalue_ref = cost_func_vqe(
    result.x, raw_ansatz, observable_1, estimator
)
print(experimental_min_eigenvalue_ref)

should be:

experimental_min_eigenvalue_ref = cost_func_vqe(
    ref_result.x, ref_ansatz, observable_1, estimator
)
print(experimental_min_eigenvalue_ref)
