Improve Bash script readability and add color-coded output

[mostafasoufi]

This PR improves the existing Bash script by making it more human-readable and providing better user interaction through the following changes:

• Color-Coded Output: Utilizes tput to introduce colored feedback for errors, progress updates, and successful operations.

  • Red for errors
  • Green for successful operations
  • Yellow for warnings or skipped steps
  • Cyan for informational progress messages
  • Improved Readability: Added descriptive echo statements at key steps (e.g., downloading files, creating databases, etc.) to
  • make the script's execution flow clear and easy to follow.

• Progress Feedback: Each major step (WordPress installation, test suite setup, and database management) now provides clear and distinct feedback to the user.

• Confirmation for Database Recreation: The script prompts the user to confirm before deleting and recreating an existing test database, ensuring safer operation.

This enhancement will significantly improve the user experience when running the script by making the outputs more readable and informative.
