Completion of the build process 🎉

We have finally managed to produce a new build process for unity images, based on knowledge and lessons learned from the famous gableroux/unity3d docker images which accumulated over 500K pulls over the years.

Unity-CI's images will be there to fully replace those images for everyone who is upgrading their workflows, or just getting started.

Thank you always, to @GabLeRoux and countless open source contributors.
