[blocks]: Form Stepper

[Sharjun-Hussain]

Description

I wanted to suggest adding a Stepper Form component to the ShadCN UI library. This would be incredibly useful for building multi-step workflows like onboarding or checkout processes. A feature similar to the Steps component in Ant Design, with customizable steps and navigation, would be a great addition to your already amazing library.
