[rmodels] Fix glTF animation framerate calculation (#4472) (#5445)

Browse Source 
- Changed GLTF_ANIMDELAY (17ms, ~58.82fps) to GLTF_FRAMERATE (60.0fps)
- Updated frameCount calculation: (animDuration * 60) instead of (animDuration * 1000 / 17)
- Updated time calculation: j / 60.0f instead of (j * 17) / 1000.0f

This fixes animation frame count misalignment when importing glTF models
exported at standard 60fps. Animations that were 27+ frames shorter than
expected on 1350-frame sequences will now import correctly.
