Checks for hreflang link elements

## Solution

Hreflang tags tell search engines about language and regional variations of pages, preventing duplicate content issues and ensuring users see the right version. Add hreflang link tags for each language/region version of a page. Include x-default for the fallback. Every page referenced should link back to all variants (bidirectional). Use correct ISO language and country codes.
