GIST Ground Truth Data Missing

[wahajali]

I want to run the Search Performance Test on the GIST dataset. I created a new test, since current workloads don't have GIST as part of the performance test. Currently GIST and SIFT are only used in capacity test.

However, the dataset doesn't contain the ground truth data. It only downloads train.parquet and doesn't download the ground truth data (I believe that would be neighbors.parquet).
