Documentation needs updating

[ilibilibom]

Hi
The documentation is not updated with the latest RN version.
there is no getPackages() method in MainActivity.java

Thanks for this awesome package

You must set this config to MainApplication.java in your project

Document is wrong

Import the package

+ import net.zubricky.AndroidKeyboardAdjust.AndroidKeyboardAdjustPackage;

Add the package to the getPackages method

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
        ...
+        new AndroidKeyboardAdjustPackage()
    );
}
