feat: add updateInsets public function to uniwind

[divineniiquaye]

Summary

Introduces an updateInsets method to both common and native UniwindConfigBuilder classes. The native implementation updates runtime insets and notifies listeners, while the common version is a no-op. This prepares the config for dynamic inset management.

Impact

This is to add support for class names using the *-safe. The root layout for a react native app is wrapped with SafeAreaListener from react-native-safe-area-context and called in the onChange prop:

<SafeAreaListener
      onChange={({ insets }) => {
        Uniwind.updateInsets(insets);
      }}
    >
    ...
 </SafeAreaListener>

Amazing! Thanks for PR, didn't knew that there's some kind of onChange method in react-native-safe-area-context 🚀
