Title step not updating bug fixed.

[turingAlan]

Description

Previously the onChange function which was responsible for the step update was being passed to the onChange prop of Stepper component of Material UI which was not causing any change to the current step. What I did is to pass that onChange function to the onClick of the StepButton which caused the active step value to change.

This PR closes #922 .

Motivation and Context

The changes that user did on title of any step only led to the change in the title of the first step as the active step index was not getting updated on the change in the active.

How Has This Been Tested?

I tested all possible ways user can edit the steps and it is working perfectly,
