Update VersionBadge to use Mintlify native Badge component (#2571)

Replace custom VersionBadge implementation with Mintlify's native Badge component while preserving custom color and border styling via CSS. This leverages Mintlify's built-in sizing, typography, and icon support while maintaining the original visual design.
