Add Heroshot to Dev Tools > Docs section

[omachala]

Hi! I'd like to add Heroshot to the Dev Tools > Docs section.

Heroshot is an open-source CLI tool for automating documentation screenshots with a dedicated Vue component integration (heroshot/vue).

Features:

• Vue component (<Heroshot>) for marking screenshot regions
• Theme-aware captures (light/dark mode)
• Config-based workflow - define screenshots once, update forever
• Works with VitePress, VuePress, and custom Vue apps

It fits well alongside vue-styleguidist and vuese as it helps create visual documentation for Vue projects.

Thank you for maintaining this awesome resource!
