Link broken for PCQM-Contact

[jiaqingxie]

Hi.
I found that the link for downloading PCQM-Contact seems to be broken,
which is
self.url = 'https://datasets-public-research.s3.us-east-2.amazonaws.com/PCQM4M/pcqm4m-contact.tsv.gz'
at line 294 in pcqm4mv2_contact.py. Could you please check that? Thanks.

I also open the same issue in GraphGPS repo, where you could double check this issue.
Thanks.

You can also check the LRGBDDataset interface offered in PyG, which also offers the PCQM-Contact dataset. However, that is not offered in .tsv format but in .pt or .pickple for other datasets.
