Change os.Setenv to test.Setenv in config_test.go
What does this MR do and why?
Workhorse codebase contains a os.Setenv
usage as well: https://gitlab.com/gitlab-org/gitlab/-/blob/32d7efd86bea87b1e25ea145988b76053f4c13b1/workhorse/internal/config/config_test.go#L153-154. It would be cool to fix it but it's probably too small for a separate issue in gitlab-org/gitlab
project
