Fix #25088 This PR adds the support for [`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) workflow trigger. `pull_request_target` is similar to `pull_request`, but the workflow triggered by the `pull_request_target` event runs in the context of the base branch of the pull request rather than the head branch. Since the workflow from the base is considered trusted, it can access the secrets and doesn't need approvals to run.
