fix: restart firewalld only when it was running
in !187 (merged) we enable the firewalld.service and also restart it. But we don't have to restart if it was not enable and running since we only change firewall rule when it was enable and running
Gitlab will be upgraded from 18.9.6 to 18.11 Wednesday evening (20260617). Expect services to be down starting 6:00PM CT (1800) for approximately 1 hour. See the following release notes:
