Add missing COMPONENTS build arg in CI
While investigating for https://gitlab.com/gableroux/unity3d-gitlab-ci-example/issues/14
I found in the CI logs that COMPONENTS
argument wasn't passed by the CI
and default string was always used:
Unity,Documentation,Android,iOS,Mac-Mono,WebGL,Windows-Mono,Facebook-Games
It did not prevent default images from working, but specifying -windows or -mac for the docker images certainly did not improve download speed.
Should be ok with this fix now
