fix: update layout classes for better responsiveness

[deleonio]

This pull request focuses on improving the layout and spacing of components in the sample React application by standardizing the use of flexbox and adjusting gaps between elements. Additionally, it includes a minor cleanup in the SCSS file to simplify styles.

Layout and Spacing Improvements:

• Updated the className for multiple components (BadgeBasic, BadgeButton, ButtonBaselined, LinkButtonBasic, LinkButtonAriaDescription, and TreeBasic) to use flex-wrap for better responsiveness and standardized the gap to gap-2 for consistent spacing.

SCSS Cleanup:

• Removed unused and redundant styles in the .indented-text class, simplifying the CSS by eliminating custom font-family, borders, and padding.
