Remove aws ossci metrics upload keys from rocm (#107613)
@huydhn
Our current workflow is to upload to GH and then upload from GH to S3 when uploading test stats at the end of a workflow.
I think these keys could be used to directly upload from the runner to S3 but we don't do that right now.
I'm not sure how high priority they keys are.
Rocm artifacts can still be seen on the HUD page
