Lumina Image 2.0 minor issue

[nitinmukesh]

Describe the bug

Error during inference: height and width have to be divisible by 8 but are 1080 and 1920

Should be 16 instead of 8.
Minor issue, can be fixed later.

Reproduction

Simply pass width = 1920 and height=1080

Logs

Error during inference: `height` and `width` have to be divisible by 8 but are 1080 and 1920.

System Info

N.A.

I think fix could be
diffusers/src/diffusers/pipelines/lumina2/pipeline_lumina2.py

Line: 382

Replace
raise ValueError(f"height and width have to be divisible by 8 but are {height} and {width}.")

with
raise ValueError(f"height and width have to be divisible by {(self.vae_scale_factor * 2)} but are {height} and {width}.")

I think the issue is with template which is used for new pipeline creation and hence some new pipelines get this issue.
