DynamicCFG timesteps seems not correct in SAT version

[mhh0318]

Here looks like a small bug for SAT version, which will cause incorrect step arg pass to dynamic cfg.

Good news is Diffusers version is correct. https://github.com/huggingface/diffusers/blob/8cdcdd9e32925200ce5e1cf410fe14a774f3c3a6/src/diffusers/pipelines/cogvideo/pipeline_cogvideox.py#L683
