   ------------------------
   This pull request addresses issue #32884 by adding support for deserializing 
`Map` types in the `JsonToRow` transformer within the Apache Beam Java SDK. The 
motivation stems from improving compatibility with workloads that ingest data 
into Iceberg tables, where `Map` types offer better read performance compared 
to JSON strings.
