Explicitly install OpenShift CLI tools as not included in latest GitH…

…ub Runner image [DI-396]

The latest GitHub `ubuntu-24.04` runner image [no longer includes the OpenShift CLI](actions/runner-images#10636), which has cause [unexpected action failures](https://github.com/hazelcast/hazelcast-docker/actions/runs/12684539163):
`oc: command not found.

Changes:
- Explicitly install the OpenShift tools [(as per `hazelcast-platform-operator)](https://github.com/search?q=repo%3Ahazelcast%2Fhazelcast-platform-operator%20redhat-actions%2Fopenshift-tools-installer&type=code)
- Replace explicit `oc login` command (requiring the `oc` binary) with cross-platform action

Fixes: [DI-396](https://hazelcast.atlassian.net/browse/DI-396)

Post-merge actions:
- [ ] backport to maintenance branches
