packer_hello_world_example_test.go fails on Apple Silicon

[fex01]

The "Hello World" Packer example and matching test "packer_hello_world_example_test.go" fail if the host plattform is not linux/amd64. The cause is easy to determine - the example does use the image gruntwork/ubuntu-test:16.04, which is only available for amd64-platforms. Such running the test will first result in the warning WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested before the expected text "Hello, World!" is returned, resulting in a failed test:

Leaving aside the question if the example should be updated to fix the problem - how would that problem be handled in a real world scenario? Exchange the base image for an image supporting multi-platform builds? Could the test be updated in a way to except the warning and such be succefull both on amd64 and arm64 hosts? Could we somehow suppress the warning? Any other advise?
