Unblocks CI jobs running in github-runner pods (e.g. FlowerCore.Print.Web
`help-screenshots`) from reaching selenium-hub. Previously the session
POST was DNAT'd to the hub pod IP then dropped at the Calico ingress
hook, surfacing as a 60s timeout against
http://selenium-hub.selenium.svc.cluster.local:4444 while the Selenium
UI showed 0/4 sessions.
