🎨(react) update storybook theme colors and refactor theme structure

This commit updates the theme colors in the Storybook configuration to
use the new global color definitions. The changes include replacing
greyscale colors with their corresponding gray colors for consistency.
Additionally, the theme structure has been refactored to align with the
updated token architecture, enhancing maintainability and ensuring a
cohesive design system across the application.
