GitLab 18.2.2 introduced a security restriction that only allows
uploading artifacts to the user's own namespace.
To work around this, hardcode the artifact location to the path where
the artifacts were uploaded to in
ce0d4f998d ("ci: Fix for GitLab 18.2.2 upgrade").
This is an ugly but temporary workaround until a proper solution is in
place.
