    // This job needs to be run only once.
    // Set the Space UNITY_USERNAME and UNITY_PASSWORD secrets to generate an activation file.
    //
    // After run:
    // 1. The activation file is echoed to build output, and should be saved as *.alf
    // 2. Visit https://license.unity3d.com/manual
    // 3. Upload the file in the form
    // 4. Answer questions (unity pro vs personal edition, both will work, just pick the one you use)
    // 5. Download 'Unity_v2019.x.ulf' file
    // 6. Copy the content of 'Unity_v2019.x.ulf' license file contents to the Space secret UNITY_LICENSE
