test code on diffusers 0.35.0 dev failed.

there are some bugs:

1. AttributeError: 'NoneType' object has no attribute 'expected_components'
2. cannot import name 'PipelineBlock' from 'diffusers.modular_pipelines'

to fix them in YiYiXu/WanImageProcessor:

1. rename config.json -> modular_config.json
2. rename PipelineBlock -> ModularPipelineBlocks in block.py

diffusers 0.36.0.dev0 failed
blocks is None, no default blocks class found for ModularPipeline

Blurred beach scenery forms the background featuring crystal-clear waters, distant green hills, and a blue sky dotted with white clouds. The cat assumes a naturally relaxed posture, as if savoring the sea breeze and warm sunlight. A close-up shot highlights the feline's intricate details and the refreshing atmosphere of the seaside."
