🐛 Describe the bug

Since https://github.com/huggingface/transformers/pull/43514 from transformers==5.4.0, either of these imports:

from vllm.model_executor.models.qwen3_vl import Qwen3VLForConditionalGeneration
# Or any module that transitively imports from qwen3_vl:
from vllm.model_executor.models.qwen3_5 import Qwen3_5MoeForCausalLM

Are now forced to eat:

[transformers] `Qwen2VLImageProcessorFast` is deprecated. The `Fast` suffix for image processors has been removed; use `Qwen2VLImageProcessor` instead.

This issue about is resolving this internal deprecation by renaming to a non-Fast class:

---from transformers.models.qwen2_vl import Qwen2VLImageProcessorFast
+++from transformers.models.qwen2_vl import Qwen2VLImageProcessor
