Adds the `Image` component from Next.js to display a local image in the
BlogPost component. The local image file `retrofuturism.webp` is added to
the `public/images` directory and referenced in the component.
This commit introduces a new `BlogArea` component that displays a list of blog posts. The changes include:
- Added a new `BlogArea` component in `components/blogpost.tsx` that renders a list of blog posts with their title, description, and a link to the full post.
- Integrated the `BlogArea` component into the `Home` page in `app/page.tsx`.
- Added mock data for the blog posts in `app/page.tsx` to demonstrate the functionality.
