Incorrect Paper Link in RayAabIntersection Class Documentation

[TT432]

I noticed that the RayAabIntersection class in the JOML library references a paper via a URL, but the link appears to be incorrect or broken.

• Class/Method: RayAabIntersection
• Issue: The paper URL included in the documentation is not accessible or leads to an incorrect page.
• Expected Behavior: The URL should link to the correct research paper or resource that explains the method or theory used in the class.
• Correct Link: https://www.cg.cs.tu-bs.de/upload/publications/fast-rayaxis-aligned-bounding-box-overlap-tests-using-ray-slopes.pdf
