Runner ID displays partition prefix

Summary

New gitlab runner tokens generated in Gitlab include partition prefix: gitlab!168017 (merged) Sample: glrt-t1_...

This gets included in generated pod name with the Kubernetes executor, sample: runner-t1{part of id}-project-{project id}-concurrent-0-{random suffix}

Steps to reproduce

Register a new runner and run a job on it, check pod name.

Actual behavior

Pod name includes partition prefix.

Expected behavior

Pod name does not include the prefix. Atleast for us the fact that it is included breaks monitoring and observability. Ultimately as an end user, this partition is not something I care about and do not thing it should be displayed.

Relevant logs and/or screenshots

Environment description

Kubernetes runner in a GKE cluster.

Used GitLab Runner version

Running with gitlab-runner 17.8.3 (690ce25c) on runner-{id}-7-gitlab-runner-77764d47d4-nhvrg t1_{part of id}, system ID: r_{redacted}

Possible fixes

I believe it is this MR in Gitlab: gitlab!168017 (merged)

This one tries to hide it: gitlab!168163 (merged) (but I think there was a bug and another MR, cant find it anymore)
