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.

-Generate a new Docusaurus site using the **classic template**.
+## Installation
 
-The classic template will automatically be added to your project after you run the command:
+See [Installation](installation.md) for instructions on adding CherryPick to your Dart/Flutter project.
 
-```bash
-npm init docusaurus@latest my-website classic
-```
+---
 
-You can type this command into Command Prompt, Powershell, Terminal, or any other integrated terminal of your code editor.
+CherryPick is open-source. Contributions and questions are welcome!
 
-The command also installs all necessary dependencies you need to run Docusaurus.
-
-## Start your site
-
-Run the development server:
-
-```bash
-cd my-website
-npm run start
-```
-
-The `cd` command changes the directory you're working with. In order to work with your newly created Docusaurus site, you'll need to navigate the terminal there.
-
-The `npm run start` command builds your website locally and serves it through a development server, ready for you to view at http://localhost:3000/.
-
-Open `docs/intro.md` (this page) and edit some lines: the site **reloads automatically** and displays your changes.
