[Bug][CDC][Postgres] Postgres-CDC fails with UnsupportedOperationException: Unsupported type TIMESTAMP_TZ for TIMESTAMP WITH TIME ZONE columns

### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues.

### What happened

When using Postgres-CDC on a table containing a PostgreSQL TIMESTAMP WITH TIME ZONE (TIMESTAMPTZ) column, SeaTunnel fails during source initialization.

The job never starts processing records and fails while building the CDC deserialization schema.

Actual behavior:

Source initialization fails with:
