Replacing GITHUB_TOKEN with PAT

Since the permissions for `GITHUB_TOKEN` are [limited](https://docs.github.com/en/actions/reference/authentication-in-a-workflow#about-the-github_token-secret) to the repository that contains the workflow, it won't be possible to use `GITHUB_TOKEN` to access other private repositories. Instead, until [centrally managed workflows](https://github.com/github/roadmap/issues/98) are implemented, users would need to create and us a PAT to access other private repositories from a workflow.
