DS Epic: Step Progress Bar

### **Description**

A Step Progress Bar is a UI component that visually represents the stages of a multi-step process, indicating the user's current position and progress through each step. It enhances user navigation and clarity by showing completed, current, and upcoming steps in a sequential manner.

The issue names no implementation files, tests, or entry points. Start by locating the design system's component structure and clarifying the required completed, current, and upcoming states for the multi-step process. Done means a Step Progress Bar component represents those stages and has agreed behavior and presentation.
