Update perf smoke test threshold in check_hf_bert_perf_csv.py (#96772)
Reduce the threshold a little further due to runner to runner performance variations. e.g. https://github.com/pytorch/pytorch/actions/runs/4419276220/jobs/7747985757 https://github.com/pytorch/pytorch/actions/runs/4419548525/jobs/7748553775 failed to meet 1.145 but were above 1.140.
