Try to test our pipeline...

Created by: daxmc99

This is an attempt to test our build pipeline...

In the spirit of untested code is broken code I tried to add some testing to make sure that main always creates the final insider images.

I'm not sure if this should be merged but it should illustrate either my lack of Go skills or that we should consider a different approach to our buildkite config generation. I personally think this could be done much better by a DAG approach used by other CI systems like Tekton. This would allow config issues to be caught at "compile-time" rather than "build-time".
