Pull request overview

This PR adds client-side redirects to the Gesture Handler documentation to ensure old gesture documentation links continue to work after the naming convention change from version 2.x to 3.x (where gesture pages were renamed from {gesture}-gesture to use-{gesture}-gesture).

Changes:

• Added @docusaurus/plugin-client-redirects dependency (version 3.7.0)
• Created redirects.json with 11 redirect mappings for renamed gesture pages and relocated documentation
• Configured the redirect plugin in docusaurus.config.js and corrected the plugin name from "reanimated" to "gesture-handler"
