Description
This PR builds on another PR opensearch-project/OpenSearch#16957. In the other PR we added a new Setting property UnmodifiableOnRestore to prevent settings from being modified on restore. So in this PR we're adding that new UnmodifiableOnRestore property to the index.knn setting to prevent it from being modified or removed on restore snapshot.
