Add example for github actions
There is a github clone of this project located here:
http://github.com/gableroux/unity3d-ci-example/
At first, it was to test travis integration, but there seem to be some interest around github actions so it would be nice to also provide such an example :)
Github also announced they will be using "Self-Hosted (coming soon): Free" which is interesting (gitlab-ci already has this)
Here's something I tried recently, it's a draft, but it would be interesting to have this in here too:
