chore(ci): streamline admin approval check in GitHub Actions workflow

Updated the GitHub Actions workflow to remove unnecessary installation of jq for checking admin approval on pull requests. The GH_TOKEN environment variable is now set directly in the job, improving the efficiency of the workflow. This change simplifies the process and reduces the overhead of installing additional packages.
