The tutorial of converters needs to explain how solutions are interpreted

What is the expected enhancement?

The tutorial of converters explains how we apply convert only. But, it is also important how we interpret solutions from the converted problem to the original problem. Moreover, we need to explain that users don’t need to use converters manually in most cases and the algorithms apply converters properly.

You can work on it if you wish. I suggest checking out the guide first and investigate the details of interpret.

Somewhat related, it would also be very nice if the documentation explained any special considerations to consider when choosing the order in which to apply multiple converters. For instance, in the constructor to QuadraticProgramToQubo:

https://github.com/Qiskit/qiskit-optimization/blob/d3bcf30941010068dc89031bb0a2cd5bc1835b7c/qiskit_optimization/converters/quadratic_program_to_qubo.py#L48-L56

Is there any particular reason that IntegerToBinary is before LinearEqualityToPenalty yet is after LinearInequalityToPenalty and InequalityToEquality?

(Ideally, there should also be a comment at that location in the code to explain why the above order makes sense there.)
