Greptile Overview

Greptile Summary

This PR fixes broken internal documentation links that were causing 404 errors when users navigated via Algolia search. The changes update link paths across two documentation files to reflect a reorganization of the user guide route structure: features previously under /functions/ are now correctly routed to either /integrations/ (for emails, API/webhooks) or /collaboration/ (for notes, tasks). Specifically, four links in what-is-twenty.mdx are updated (Email Integration, Notes, Tasks, and API & Webhooks), and one link in integrations.mdx is corrected (API key generation). This is a pure documentation maintenance change that aligns internal links with the actual file locations and routing structure, ensuring users can successfully navigate to referenced content pages.
