Reset runners registration token button unrecoverable.
In the Admin Area > Runners, clicking the Reset runners registration token button generates a new smaller token. Shared runners can no longer be provisioned with the helm chart. There is no mechanism to re-provision a new token using the helm upgrade command. It seems that removing the runner-secret will cause a new secret to generate from
./charts/shared-secrets/templates/_generate_secrets.sh
Gitlab runner secret
generate_secret_if_needed {{ template "gitlab.gitlab-runner.registrationToken.secret" . }} --from-literal=runner-registration-token=$(gen_random 'a-zA-Z0-9' 64) --from-literal=runner-token=""
but this doesn't match the new token that GitLab generated.
