[JAVA] [arrow-jdbc] Unmapped data type 2014 (TIMESTAMP_WITH_TIMEZONE)

### Describe the usage question you have. Please include as many useful details as possible.

I have an iceberg table with column type "TIMESTAMP_WITH_TIMEZONE"

When I run my flight_sql jdbc client to query this table, I get below error in my flight sql client code.

```
Exception in thread "Thread-0" java.lang.RuntimeException: java.sql.SQLException: Error while executing SQL "SELECT * FROM datawarehouse.school_data_raw.schools limit 100": Unknown error: java.lang.UnsupportedOperationException: Unmapped JDBC type: 2014

Query I am running is **SELECT * FROM datawarehouse.school_data_raw.schools limit 100**

Table structure is :

_CREATE TABLE datawarehouse.school_data_raw.schools ( school_id varchar, school_name varchar, ingested_at timestamp(6) with time zone ) WITH ( format = 'PARQUET', format_version = 1, location = 's3a://data-warehouse/raw/school_data/schools' )_

### Component(s)

Java

まず、ArrowFlightMetaImpl.prepareAndExecute に示されている準備の経路を、ArrowFlightSqlClient と type 2014 に対する JDBC メタデータ処理まで追跡します。TIMESTAMP_WITH_TIMEZONE 列に対して SELECT クエリを再現し、その JDBC type に期待される動作を特定します。クエリが unmapped-type error で失敗しなくなり、coverage でそれが検証されれば完了です。
