[Bug]: WinCLIP export pytorch model issue

[junxnone]

Describe the bug

WinCLIP cannot export pytorch model

Dataset

MVTec

Model

Other (please specify in the field below)

Steps to reproduce the behavior

from anomalib.data import MVTec
from anomalib.models import WinClip
from anomalib.engine import Engine
from anomalib.deploy import ExportType
      
datamodule = MVTec()
model = WinClip()

engine = Engine()
engine.fit(datamodule=datamodule, model=model)
engine.export(model, export_type=ExportType.TORCH)

OS information

OS information:

• OS: [e.g. Ubuntu 22.04]
• Python version: [e.g. 3.10.13]
• Anomalib version: [e.g. main branch]
• PyTorch version: [e.g. 2.3.1]
• CUDA/cuDNN version: [e.g. 12.1]
• GPU models and configuration: [e.g. 2x GeForce RTX 3060]
