Gitlab Runner 15.3.0 fails to pull the gitlab-runner-helper image from the Gitlab registry

Summary

Using GitLab Runner 15.3.0 installed on a VM using Docker runner, all CI job fails with the following error message

Using Docker executor with image python:3.10-bullseye ...
Pulling docker image registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-bbcb5aba7 ...
WARNING: Failed to pull image with policy "always": Error response from daemon: manifest for registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-bbcb5aba7 not found: manifest unknown: manifest unknown (manager.go:235:0s)
ERROR: Job failed: failed to pull image "registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-bbcb5aba7" with specified policies [always]: Error response from daemon: manifest for registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-bbcb5aba7 not found: manifest unknown: manifest unknown (manager.go:235:0s)

The error disappeared when setting the helper_image to registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-e0218c92, which I got from #28973 (closed).

Environment Description

The runner was installed on a Gentoo Linux VM from the official Gentoo ebuilds.

Used GitLab Runner Version

This version does not work for me

Version:      15.3.0
Git revision: bbcb5aba7
Git branch:
GO version:   go1.19.1
Built:        2022-09-16T12:10:52+00:00
OS/Arch:      linux/amd64

Possible Fix

Explicitly setting helper_image in the runner's config.toml to registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-e0218c92 fixes the issue. Got this from #28973 (closed).
