Bug description

@jsm174 Here is where the linux images are created: https://github.com/game-ci/docker/blob/main/images/ubuntu/editor/Dockerfile

I just ran into this issue as well.

I found a post on the unity forums: https://forum.unity.com/threads/linux-command-line-build-of-macos-has-wrong-mono-path.1200499/

I tried that solution and made a custom image with the following:

FROM unityci/editor:2021.2.13f1-mac-mono-0
RUN ln -s /opt/unity/Editor/Data/PlaybackEngines/MacStandaloneSupport/Variations/macos_x64arm64_player_nondevelopment_mono /opt/unity/Editor/Data/PlaybackEngines/MacStandaloneSupport/Variations/macos_x64ARM64_player_nondevelopment_mono

@webbertakken, I can create a PR with this fix. Can you point me to where the Docker images are created?
