feat(Images): convert images to AVIF format for improved performance

- Updated image references in various components and configuration files to use AVIF format instead of PNG and JPG.
- Modified the build process to include a script for converting images to AVIF, enhancing loading times and reducing file sizes.
- Ensured consistency across the application by updating image paths in the footer, main layout, and content components.
