Fix weight download URLs

[NicolasHug]

Fixes #7744

TL;DR: some hash were wrong. After #7219 got merged, we started getting (expected) errors on those links.

This PR fixes the hashes/links. I re-uploaded the proper weights with the proper hashes on S3.

Script used to check all weights can be downloaded properly:

import torchvision.models


problems = []
for name in torchvision.models.list_models():
    print(name)
    kwargs = {"quantize": True} if "quantized" in name else dict()
    for weights in torchvision.models.get_model_weights(name):
        print(weights)
        try:
            torchvision.models.get_model(name, weights=weights, **kwargs)
        except RuntimeError as e:
            problems.append((name, weights, e))
            print(e)

print("Following models need to be fixed:")
for name, weights, e in problems:
    print(name, weights, e)
