This commit introduces the layout and page components for the blog post feature.
The main changes include:
- Implement the `RootLayout` component in `app/blogpost/layout.tsx` to provide the overall structure and styling for the blog post pages.
- Implement the `PostPage` component in `app/blogpost/page.tsx` to display the content of a specific blog post, including the post title, metadata, and the post body (template).
- Add placeholder content and styling for the blog post page, including the use of the `Image` component to display a featured image.
These changes lay the foundation for the blog post feature, allowing users to view and interact with individual blog posts on the website.
