Pull Request Overview

This PR adds documentation for a new delay prop on the TooltipV2 component. The prop allows developers to configure the delay before showing a tooltip with predefined timing options.

• Added delay prop documentation to Tooltip.docs.json with three predefined options: 'short' (50ms), 'medium' (400ms), and 'long' (1200ms)
