Updates markdown headers in development files

Updates markdown headers in development files to improve consistency and readability.

Removes the redundant "🔧 DEVELOPMENT" headers and standardizes the subsequent headers to indicate the purpose of the following code, such as "🧪 Test Your Matrix Multiplication". This change enhances the clarity and organization of the development files.
