Pull Request Overview

This PR adds support for custom page description metadata generation through front matter in MDX files. Previously, pages relied on default metadata; now authors can specify custom descriptions directly in the front matter to improve SEO and provide more accurate page summaries.

• Added description field support in MDX front matter processing
• Enhanced metadata generation logic to use custom descriptions when available
• Updated the End-of-Life page with a descriptive summary
