refactor(tutorial-card): remove read-instructions step and simplify completion logic

Eliminate the read-instructions step component and associated markup to 
streamline the second stage tutorial card. Update completion logic to only 
track the implement-solution step, removing redundant state and analytics 
tracking for read-instructions. This reduces complexity and improves UI 
clarity by focusing on the most important step users need to complete.
