fix: resolve :target: and :zoom: conflict in image examples (#506)

- Example 1: Remove :zoom: lightbox (demonstrates :target: for external links)
- Example 2: Remove :target: (demonstrates :zoom: lightbox for zoom functionality)

The :target: and :zoom: options conflict with each other. This change
provides clear examples of both features without conflict.
