[Improvement] Add exception message for gravtinio trino connector: Hive CSV storage format only supports VARCHAR

### What would you like to be improved?

### How should we improve?

Pop clear exception message like hive connector as following:

io.trino.spi.TrinoException: Hive CSV storage format only supports VARCHAR (unbounded). Unsupported columns: congress integer, birthday date, termstart date, age double

The issue names no source file, test, or entry point. Locate the Gravitino Trino connector's Hive CSV schema validation and compare its error handling with the Hive connector example in the issue. Done means unsupported non-VARCHAR columns produce a clear exception listing the columns and stating that Hive CSV supports only unbounded VARCHAR.
