`Job failed (system failure): context deadline exceeded` after runner update
## Summary
As described by @kakawait in the [forum thread here](https://forum.gitlab.com/t/high-number-of-error-job-failed-system-failure-context-deadline-exceeded-since-19-1-0/134287), after updating to GitLab runner 19.1.0, we're experience CI failures:
```
ERROR: Job failed (system failure): context deadline exceeded
```
This is a follow-up to [this discussion](https://gitlab.com/gitlab-org/gitlab-runner/-/work_items/39426#note_3478872728)
_TBD: details follow_

## Actual behavior
What actually happens: sometimes when saving artifacts for next step, sometimes when getting artifacts from previous step the job fails
with: `Job failed (system failure): context deadline exceeded`
## Expected behavior
`Job succeed`
