Fix DedicatedClusterSnapshotRestoreIT.testSnapshotWithStuckNode that is failing with reproducible seed

[cwperks]

Description

Fails consistently with:

./gradlew ':server:internalClusterTest' --tests "org.opensearch.snapshots.DedicatedClusterSnapshotRestoreIT.testSnapshotWithStuckNode" -Dtests.seed=565D3205AE4EEC96 -Dtests.security.manager=true -Dtests.jvm.argline="-XX:TieredStopAtLevel=1 -XX:ReservedCodeCacheSize=64m" -Dtests.locale=uz-Cyrl -Dtests.timezone=Australia/Victoria -Druntime.java=23 -i

This small changes fixes the failing seed, but I'm not quite sure why.
