Add scale3d() CSS transform function entry

[Pablo-Devs]

Description

I have created a new term entry for the CSS scale3d() transform function. This entry provides comprehensive documentation for the 3D scaling transform function that allows developers to scale elements along the x, y, and z axes in 3D space.

Files Created:

• content/css/concepts/transform-functions/terms/scale3d/scale3d.md

Content Includes:

• Clear description of the scale3d() function's purpose and capabilities
• Detailed syntax explanation with parameter descriptions
• Practical example showing how to scale a cube element in 3D space
• Interactive Codebyte example demonstrating the function with hover effects
• Proper metadata following the term entry template standards

This addition fills a gap in the CSS transform functions documentation by providing a dedicated entry for the 3D scaling function, which was previously only mentioned in the general transform entry but lacked its own detailed documentation.

Hey @Pablo-Devs, thank you for contributing to Codecademy Docs! The entry looks amazing!

However, just a few modifications are required:

• please add the image/gif of the output in this entry and place it inside the media folder in docs
• please explain the examples. A one line description before the code would be good,

Let me know once you make these changes. Thank you! 🚀
