extend "topology change coordinator fiber got error std::runtime_error" for disrupt_terminate_and_replace_node nemesis

[Argus](https://argus.scylladb.com/test/b188a1f4-47cc-4fb3-b6b4-7c6428910c5f/runs?additionalRuns[]=62e9ade2-6235-4cd4-a8d9-d0b0eabf88ae) Scylla version: `2026.1.0~rc0-20260125.f94296e0ae43` with build-id `9680213fda6f301234c43da8ca27e47953987cd8` Now **ignore_raft_topology_cmd_failing** only wraps **_terminate_cluster_node** and stays active for just 30s after that call finishes. But then nemesis does sleep(300) and continues with the replace process.
