Solution found in - actions/github-script#242

In V5 of this action, we upgraded Octokit and REST methods now need to be referenced by github.rest - https://github.com/actions/github-script#breaking-changes-in-v5

This should be github.rest.actions.listWorkflowRunArtifacts rather than github.actions.listWorkflowRunArtifacts
