feat(tutorial): add silentErrors prop to suppress error messages

Add silentErrors prop to TutorialPlayer to allow suppressing "That's not
the highlighted bead" error messages. Used on homepage to provide a less
intrusive demo experience.

Changes:
- Add silentErrors prop to TutorialPlayerProps interface
- Conditionally skip error dispatch when silentErrors is true
- Pass silentErrors={true} from homepage TutorialPlayer
