Add react-native-earl-gamepad to libraries list

[Swif7ify]

Added new library entry for react-native-earl-gamepad with images.

📝 Why & how

Adding react-native-earl-gamepad to the directory.

Why: Existing React Native gamepad libraries are largely outdated, unmaintained, or incompatible with modern RN versions.

How: This library uses a WebView-based bridge to access the standard HTML5 Gamepad API, exposing buttons, axes, D-pad, and connection events to React Native with a modern hook-based API.
