pause duration affects the first frame

```
AnimatedTextKit(
animatedTexts: [
TypewriterAnimatedText('................................'),
],
pause: const Duration(seconds: 7), // <--- have to wait for 7 seconds to see the text '...........'
repeatForever: true,
)
```

Look at the AnimatedTextKit widget and its pause parameter handling, likely in lib/src/animated_text_kit.dart. Examine how the initial animation delay is applied, particularly for TypewriterAnimatedText. Test by running the provided example and modifying the pause logic to ensure the first frame appears immediately before the pause takes effect.
