feat: Hide example output with details shortcode

[ADubhlaoich]

Proposed changes

This pull request hides the example output of commands using the Hugo details shortcode. It is an interactive element that is closed by default. Since the example output is optional, this reduces the amount of visible noise on the page, making it faster to read.
