GitLab image compatability

[dudeisbrendan03]

Maybe on oversight on my part and I've missed out something, I will upload my Ci/Cd file showing my usage of snyk later today.

It appears the GitLab runner can't run custom images properly, failing to run exec on the entry point, however eval works

I'm not in a position to run my own image on the pipeline at the moment so can't really test it, but I was wondering if I had made a configuration mistake, and if not is it possible to change exec -> eval here without repercussions to other platforms where this is already functional, like GitHub Actions, CircleCI, etc.
