Shift_factor is not used in sd3 training.

[laksjdjf]

In img2img pipeline, vae'output substracted by shift_factor.

diffusers/src/diffusers/pipelines/stable_diffusion_3/pipeline_stable_diffusion_3_img2img.py

Line 629 in f1f542b

init_latents = (init_latents - self.vae.config.shift_factor) * self.vae.config.scaling_factor

But not substracted in training.

diffusers/examples/dreambooth/train_dreambooth_sd3.py

Line 1547 in f1f542b

model_input = model_input * vae.config.scaling_factor

Is thig bug?
