refactor: update Sanity schema and types for image and file assets

- Introduced new types for `CoverImage` and `VideoCloudinary` in `types.ts`.
- Updated `extract.json` to include new asset references and attributes.
- Modified `avatar.tsx` to use the `name` for the alt attribute of images.
- Cleaned up `pnpm-lock.yaml` by removing unused Cloudinary dependencies.
