grant directory-migrate workflow permission to push to fork #4371
Description
I ended up linting and adding migration for #4366 manually. Since refactoring away from Azure DevOps Pipelines to GitHub Actions, the directory-migrate.yml doesn't have permission to push the new migrations back to the fork's branch.
I researched some. Maybe pull_request_target would work, but there are security concerns.
Google-fu is just failing me today on how to get this working. Will address at some point soon.
