GHA: Re enable mac json uploads (#69387)
Summary:
Removed JSON uploading to S3 for Mac GHA workflows as the AWS credentials were not working.
This PR tries uploading them to GitHub instead, which works https://github.com/pytorch/pytorch/runs/4413940318?check_suite_focus=true
They should show up on the HUD page: hud.pytorch.org/pr/69387 with the name test-jsons after the CI is completed.
