Post the changes in SERVER-84723, refineCollectionShardKey DDL op command can cause a SnapshotUnavailableError if the collection timestamp it modifies is newer than that of a txn operation in progress.

Since this snapshot error is a transient txn error, we should modify write_without_shard_key_base.js to skip validating response in this case. This can happen for other DDL operations too which modify collection timestamp.
