fix: correct repository dispatch event type name

- Change event-type from "Web: Directory listing" to "Generate website"
- Aligns with the comment above that describes the action
- Ensures consistency between the event name and its purpose

This fix ensures the repository dispatch event name accurately reflects
its function of generating the actions.armbian.com website.
