SPSA doc string out of date

[Durd3nT]

Environment

• Qiskit Algorithms version: 0.2.1
• Python version:
• Operating system:

What is happening?

The small code examples in the doc string of qiskit_algorithms/optimizers/spsa.py still show the old signature of optimizers in qiskit instead of the new scipy-style optimizers. This includes a method optimize that is now called minimize, returning point, value, niter instead of OptimizationResult objects, etc.

How can we reproduce the issue?

What should happen?

The code examples shout show the new way of using optimizers in qiskit.

Any suggestions?

Thanks for noticing and raising this issue. It is also using StateFn which was part of qiskit.opflow which was deprecated and will no longer be present in the upcoming Qiskit 1.0. The first part could be re-done showing it used with an Estimator. Though I do not know how much value there is in that given its usage is no different syntactically than any other optimizer in that regard.
