chore: update markdown dependency and configuration

- Replaced `gpt_markdown` with `flutter_markdown_plus` in `pubspec.yaml`.
- Updated `pubspec.lock` to reflect the new dependency version.
- Modified `markdown_config.dart` to generalize styling configuration.
- Updated `streaming_markdown_widget.dart` to utilize `MarkdownBody` for rendering markdown content.
