feat(website): update home page to showcase CherryPick DI documentation

- Replaced the main action button text with 'Explore CherryPick Documentation 🍒' instead of 'Docusaurus Tutorial'.
- Updated the button link to target /docs/intro (main docs entry point).
- Changed <Layout> props:
  - Page title now uses project title only (siteConfig.title)
  - Added a CherryPick-related site description for better SEO and context.
- The homepage is now tailored to reflect CherryPick's purpose as a Dart & Flutter DI library instead of Docusaurus boilerplate.

-        Docusaurus lets you focus on your docs, and we&apos;ll do the chores. Go

+        Register synchronous or asynchronous providers, named and singleton dependencies, and enjoy null-safe, testable resolution. Annotation-based code generation removes all manual “wiring”.
