Fix failing unit tests to match enhanced error messages

- Update test expectations to match the new enhanced namespace error messages that include helpful list command suggestions
- The enhanced error handling now provides more informative messages like: 'Use hyp list hyp-jumpstart-endpoint to check for available resources'
- This addresses the GitHub CI test failures while maintaining the improved user experience
