Fix CI actions running double (#54)

I have noticed that we are running workflows double on ghstack based pull requests, i think it is triggering twice due the hooks, one for push and one for pull request. Hopefully this copy-pasted from pytorch trigger fixes it. Source: https://github.com/pytorch/pytorch/blob/main/.github/workflows/lint.yml
