refactor(route): streamline Open Graph meta tag generation for bots

Browse source 
- Introduced a new metaTag function to simplify the creation of meta tags for Open Graph and Twitter.
- Replaced regex-based bot detection with the isbot library for improved accuracy.
- Enhanced the GET route to conditionally render meta tags based on available link metadata, improving SEO and social media sharing capabilities.
