Update timm torchvision resnet weight urls to the updated urls in torchvision

[JohannesTheo]

This fix updates the weight urls of timm to be in sync again with torchvision resnet*.IMAGENET1K_V1 models.

During my work, I found that resnet weight urls in timm and torchvision are different and was wondering why.

A quick search revealed that models have been re-uploaded with new serialization in 2020 (see pytorch/vision#2068 ). The new files have a different hash and hence, a different url. This PR updates the urls in timm to the updated urls in torchvision:

• ResNet18: https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py#L312
• ResNet34: https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py#L334
• ResNet50: https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py#L356
• ResNet101: https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py#L399
• ResNet151: https://github.com/pytorch/vision/blob/main/torchvision/models/resnet.py#L442

Note that the old urls are still online for BC.

In summary, it's probably not super important to change urls but at the same time, why not fix it :)

thanks, never noticed they changed those, though the safetensors weights from huggingface hub are used by default now.
