Multi-arch support for images used during integration tests

/kind bug

What versions of software are you using?

Operating System:

IBM Z architecture

Issue

During integration tests, some devfiles are using images that don't have multi-arch support and don't support Z arch.

For example: https://github.com/redhat-developer/odo/blob/main/tests/examples/source/devfiles/nodejs/devfileCompositeBuildRunDebugInMultiContainersAndSharedVolume.yaml

is using quay.io/quay/busybox:latest which is not support by Z arch.

It would be better to use this one instead: https://quay.io/repository/openshifttest/busybox
