docs: Added Figma to Flutter MCP community server

[mhmzdev]

Added Figma to Flutter MCP server repo link.

🚀 Major Features

1. 🏞️ Asset Extraction: Exports the .png .jpeg or .jpg type of assets directly into flutter project. Updates the directory and pubspec.yaml too
2. 🧱 Widget generation: Gives you actual Stateless or Stateful Widgets based on COMPONENTS from Figma's link
3. 📲 Full screen: Combining above points 1 and 2, will generate full screen. Handles asset exports automatically if includes any along with reuseable components/widgets

Motivation and Context

Its an extended version of Figma MCP that helps you write Flutter code directly from Figma design tokens.
