Greptile Summary

This PR adds comprehensive user permissions documentation to the Greptile docs by creating a new file security/user-permissions.mdx and updating the navigation structure. The documentation explains Greptile's three-tier permission system with clear definitions for Members, Admins, and Owners roles, detailing their specific capabilities and access levels.

The new documentation provides practical guidance including step-by-step instructions for managing user permissions through the admin dashboard, important notes about permission requirements, and security best practices for role assignment. The content follows standard documentation conventions with proper frontmatter, structured headings, and appropriate use of Mintlify components like the Note component for highlighting critical information.

The placement within the Security section is logical and improves discoverability, as user permissions are a fundamental security concern for organizations. The navigation update in docs.json positions the user permissions page as the first item in the Security group, making it easily accessible to administrators who need to understand and manage access controls.
