fix: Package class name regex tweaks on Android

[dratwas]

Summary:

Current regex doesn't support code like this:

class SomePackage() : ReactPackage {}

but kotlin does ;)

In this PR i added support for this

Test Plan:

Try autolinking for Andorid with package class like this:

class SomePackage() : ReactPackage {

    override fun createNativeModules(reactContext: ReactApplicationContext): MutableList<NativeModule> {
        return Collections.emptyList()
    }

    override fun createViewManagers(reactContext: ReactApplicationContext): MutableList<SimpleViewManager<View>> {
       return Collections.emptyList()
    }
}

I'd really appreciate extracting this regex to a function and adding a small unit test suite :)

Yay!
