✨ feat: upgrade to Astro v5 with compatibility and improvements

- 🗂️ Migrated content collections to the new Content Layer API:
  - Removed deprecated `type: "content"` from content collections.
  - Updated `src/content/config.ts` to use the Content Layer API.
  - Validated content files and schema using `astro check`.

- 🛠️ Updated TypeScript configuration for Astro v5:
  - Added `.astro/types.d.ts` and `**/*` to the `include` property for better type inference.
  - Excluded `dist` directory from type-checking.

- ✅ Verified overall compatibility with Astro v5 and optimized for future updates.
