Usage example of greatest common divisor

[dhruvjanghu]

Description

Added a new usage example demonstrating the greatest_common_divisor function in SplashKit.
includes version in 4 different languages.

No additional dependencies are required for this change.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

All language versions were tested locally using MSYS2 and SplashKit libraries.
Each file was compiled and executed successfully, producing the expected visual output:

• Displays the title “Greatest Common Divisor Example”.
• Shows Number A, Number B, and the GCD result.
• Pressing ESC cleanly exits the window.

No warnings or build errors occurred.

Testing Checklist

• Tested in latest Chrome (for web documentation build)
• Tested in latest Firefox
• npm run build
• npm run preview
