workload: tpcc fix alter partition query for partitioned replication

Fixes partitioning query generated with no zone config and partition strategy
as replication. Earlier we were specifying per rack replica placement information
which is not required in partitionedReplication which caused the error
bad query
- ALTER PARTITION p0_0 OF TABLE warehouse CONFIGURE ZONE USING constraints = '{+rack=0: 1, +rack=1: 1, +rack=2: 1}
  error - pq: could not validate zone config: when per-replica constraints are set, num_replicas must be set as well

Fix is to not add this per replica constraint for replication, reverting to the old way of alter partition.

Fixes: #143410
Epic: none
