[FLINK-33129] Can't create RowDataToAvroConverter for LocalZonedTimestampType logical type

• Type: Bug

Description

While creating converter using `RowDataToAvroConverters.createConverter` with LocalZonedTimestampType logical type, the method will throw exception. This is because the switch clause is missing a clause for `LogicalTypeRoot.TIMESTAMP_WITH_LOCAL_TIME_ZON`.

Code: https://github.com/apache/flink/blob/master/flink-formats/flink-avro/src/main/java/org/apache/flink/formats/avro/RowDataToAvroConverters.java#L75

 

We can convert the value to `LocalDateTime` and then `TimestampData` using method below. Then we can apply the same converter as 
TIMESTAMP_WITHOUT_TIME_ZONE? 
 
`TimestampData fromLocalDateTime(LocalDateTime dateTime)`

Can Flink team help adding the support for this logical type and logical type root?

This is now a blocker for creating Flink Iceberg consumer with Avro GenericRecord when IcebergTable has `TimestampTZ` type field which will be converted to LocalZonedTimestampType.

See error below:
