Description

We should introduce TypeCoercionTestSetup record which is used in BaseIcebergConnectorTest. Also, nested types (e.g. array(array(...))) should be tested after the refactoring.

Contributor guide

Research direction
Study the existing TypeCoercionTestSetup record in BaseIcebergConnectorTest and apply similar pattern to Delta Lake connector tests. Ensure nested types are covered.
