Getting "Error: Rate exceeded" from the aws-actions/aws-cloudformation-github-deploy action

Got `Error: Rate exceeded` from a few of the `aws-actions/aws-cloudformation-github-deploy@v2` actions.

We didn't see this from the `v1` actions, but this could be unrelated.

I don't see related options for controlling this in https://github.com/aws-actions/aws-cloudformation-github-deploy/blob/master/action.yml, so this may require a code change in the action, rather than just a configuration change in this project's use of that action.
