docs: Add AI functionality disclosure example to Tooltip docs

[mig-builds]

Summary

Resolves: #4125

Adds a new "AI Functionality Disclosure" example and docs section to the Tooltip page, showing how to use type="description" to disclose that a control triggers AI-powered functionality (e.g. "This functionality is powered by AI.") to assistive technology users, without changing the element's visible label.

Testing Manually

Docs-only MDX + example component change, following the existing example pattern in this file (e.g. DescriptionType). I could not run this repo's full yarn/lerna build and typecheck scripts in my environment, so please double-check the MDX renders as expected in Storybook.
