[Bug]: Varchar logical type fails Iceberg Pipelines

[tarun-google]

What happened?

While writing a pipeline for Postgres->Iceberg the pipeline fails when the table contains VARCHAR fields. This is because it is not added as part of BeamSchemaLogical type here. Expectation of this Bug is to review more such JDBC Datatypes that needs to be supported for JDBC->Iceberg and fix them.
