Adds a new `AnimatedLink` component that provides a smooth hover animation
effect to links. This component is then used in the `BlogArea` component to
enhance the appearance of the blog post links.
The changes include:
- Creating a new `AnimatedLink` component in `animatedLink.tsx`
- Updating the `BlogArea` component in `blogpost.tsx` to use the new
`AnimatedLink` component instead of the default `Link` component from
Next.js.
