Pull Request Overview

The PR successfully implements the documentation for the AI Risk Hub and relocates the files as requested. Codacy analysis indicates the changes are up to standards. However, the redirect logic in mkdocs.yml is currently incorrect and will result in 404 errors for existing bookmarks. Additionally, the phrasing regarding the release date needs correction to avoid ambiguity. These issues should be addressed before merging.
