gitlab-ci-multi-runner 9.5.0 pulling invalid tag for gitlab-runner-helper on OS X

Summary

Some time last night, all my pipelines started failing with the error:

ERROR: Job failed: image pull failed: rpc error: code = 2 desc = Tag x86_64-413da38a not found in repository docker.io/gitlab/gitlab-runner-helper

I am on macOS 10.12.6 running gitlab-ci-multi-runner 9.5.0 (the most up to date for my platform, as far as I'm aware). As the error suggests, there is no image for docker.io/gitlab/gitlab-runner-helper:x86_64-413da38a, there is however one with the tag x86_64-413da38. It does look like some gitlab-runner-helper images were updated last night, so my guess would be that someone accidentally deleted something or changed a tag.

Steps to reproduce

Attempt to run any CI pipeline using the kubernetes executor.

Actual behavior

Every job fails to run with an ImagePull error.

Expected behavior

The jobs should run.
