fix(tests): Update error handling in BuildPage to suppress unused variable warning

Modified the error handling in the `BuildPage` class to replace the caught error variable with an underscore (`_error`). This change prevents warnings about unused variables while maintaining the existing functionality of logging tutorial dismissal messages. Ensured that the code remains clean and adheres to best practices.
