[EXTERNAL] docs(drawing): fix implementation example for rectangle

Fix Rectangle Implementation Example

This PR updates the example usage of the Rectangle shape to correctly demonstrate a rectangle, rather than a square, as the original coordinates resulted in equal width and height.

Changes:

• Replaced:

  let rectangle = gs::Rectangle::new(&gs::Point::new(150, 150), &gs::Point::new(50, 50));

  with:

  let rectangle = gs::Rectangle::new(&gs::Point::new(150, 300), &gs::Point::new(50, 60));

Note:

This corrected example is borrowed from the rust/tests repository.

While technically squares classify as rectangles, I agree changing to a non-square example, the same as the one in the tests here makes sense. If you can, please run prettier -w on the file and push the change, as it's not prettier compliant as of right now. With that I can merge without conflicts. Thank you once again!

Closed in favor of #3016. Includes this one change and has prettier all set up.
