K8s runner: How to set a custom description?

Hello all!

I’ve set up a K8s runner via Helm…

helm upgrade --install --namespace gitlab-runner -f values.yaml gitlab-runner gitlab/gitlab-runner

… and it appears pretty quickly in the runners list, but with a generic description “gitlab-runner-gitlab-runner-…”.

How do I set a more specific description, e.g. “K8s-…”?
