[rmodels] GLTF Models deforms during an animation

[YousefAhmed-365]

Description

GLTF Model is deformed during an animation.

This issue appears to be specific to Raylib as it doesn't occur in other frameworks, engines, or GLTF viewers I tried. I have attempted to apply all transforms in Blender and experimented with various export settings, but the issue persists. This problem seems to affect random models for some reason as it didn't happen with a different model that I used in the past even though they use the same rig provided by blender's Rigify addon.

Manual weight painting seems to affect the issue, but even after doing it the elbow of the model still deforms for no reason.
