Doc: Update the documentation for row movement behavior across partitions.
In commit f16241bef7c, we have changed the behavior for concurrent updates
that move row to a different partition, but forgot to update the docs.
Previously when an UPDATE command causes a row to move from one partition
to another, there is a chance that another concurrent UPDATE or DELETE
misses this row. However, now we raise a serialization failure error in
such a case.
