Fix broken periodic workflow after removing ios secret (pytorch#85664)

Broken after pytorch#85597, i.e. https://github.com/pytorch/pytorch/actions/runs/3130970082

```
The workflow is not valid. .github/workflows/periodic.yml (Line: 189, Col: 26): Invalid secret, IOS_CERT_KEY_2022 is not defined in the referenced workflow. .github/workflows/periodic.yml (Line: 190, Col: 24): Invalid secret, IOS_CERT_SECRET is not defined in the referenced workflow.
```
