refactor(triggers): rename triggerWorkflow to onFailureWorkflow for clarity

- Updated all instances of `triggerWorkflow` to `onFailureWorkflow` across the codebase to improve clarity and consistency in naming.
- Adjusted related logic in workflow configurations and UI components to reflect the new naming convention.
- Enhanced error messages and documentation to align with the updated terminology.

This change aims to provide a clearer understanding of the workflow's failure handling mechanism.
