@angelosilvestre can you look at these changes and see if you understand what's going on?

@CillianMyles - You might get goldens to work from a Linux machine by chance, but technically we use the Docker-based runner described in the docs. We should get goldens working with that.

Also, I see that this PR changed the platform target of some tests. My initial thoughts is that that's not an appropriate "fix" because that's altering the actual thing under test.

@CillianMyles please let me know if the golden infrastructure is too difficult to use based on the docs I linked in the other PR, or if you're otherwise unable to get them generating. We'll wanna get this corrected as soon as possible given that the error is reported in every PR.

@matthew-carroll I was able to get docker and the setup for golden tests running, and successfully regenerated the goldens in both this PR, and option 2 (#2184).

I also updated the PR description for both, to help explain the difference in approach.

Please let me know if either of these PR's are okay for you, or if we should take another route. Admittedly I don't know why the goldens needed to be regenerated, but not something I had too much time spend digging into, I mostly wanted to clear the way so my other PR (#2139) can land.

I also created a PR to update the docs with some more info on installing docker (#2199).
