We can set a cron schedule to trigger a GitHub Actions workflow to stop and start Azure App Service.
Simply set Azure CLI commands to stop and start Azure App Service in separated workflows.
For example, we can have Stop Azure App Service workflow which runs every midnight (UTC+7) and Start Azure App Service workflow which runs at 6AM everyday (UTC+7).

      - name: Azure Login
        # https://github.com/Azure/login/tags
        uses: azure/login@v1
        with:
          # We don't need to set a default subscription because we get credentials from a specific subscription.
          creds: ${{ secrets.AZURE_CREDENTIALS }} #
