refactor: Update GraphitiStep to proceed to the next step after successful configuration save

- Changed behavior to call onNext() immediately after a successful save of the Graphiti configuration, enhancing user experience by streamlining the onboarding process.
- Removed the previous setSuccess() call to avoid confusion regarding the step transition.
- Remove task creation from onboarding
