feat: add RSS feed generation and update package metadata

- Implemented a new RSS feed generation feature in src/pages/feed.xml.ts, allowing users to follow blog updates.
- Updated package.json and package-lock.json to include license information and new type definitions for markdown-it and sanitize-html.
- Refactored createOgImage function to return Uint8Array instead of Buffer for better compatibility.
- Simplified pageSchema by removing the optional mainEntityId parameter for cleaner schema generation.
