Add support for macos

[Kariaro]

Context I need to test that external libraries work in Windows, Linux and Macos.

Currently macos is not supported. That's why I'm making this issue

Suggested solution

Copy code from game-ci/unity-builder that handles darwin systems and use it in this repository

Additional details

I'm going to try make a PR for this issue myself and will clone this repository to start testing

[webbertakken]

Yup! We support this approach and accept contributions.

I'm currently looking at the generated docker images for macos but I don't see any here: https://github.com/game-ci/docker/tree/main/images/macos

Should I copy the MacBuilder concept from https://github.com/game-ci/unity-builder/blob/main/src/model/mac-builder.ts and apply it so that if process.platform === 'darwin' I jump to the MacTestRunner instead?

That's right, there are no docker images for macos, so you would likely need to copy the relevant typescript code from unity-builder.

Any news here? Any help needed?
