Description

Instead of creating on the fly an Iceberg table with Trino and run queries against it, use static resources for setting up an Iceberg test environment which can be used to read Iceberg v1 / v2 tables and guard trino-iceberg plugin against regresssions.

Research direction
Review the discussion in https://github.com/trinodb/trino/pull/11642#discussion r843193907 to understand the context. Then, create static Iceberg table resources (e.g., in the test resources directory) and write tests that read from these tables to verify read ability. Look at existing test patterns in the trino iceberg module for guidance.
