Remove catalog name from the coralRelNode TableScan

[aastha25]

Currently during hive -> spark/trino Sql translations, coral creates a relNode plan. The tableScan relNode has a representation: LogicalTableScan(table=[[hive, dbName, tableName]]). When this relNode is translated to a SqlNode, "hive" (catalog name) has to be removed explicitly.

Filing this issue to investigate if introducing the catalog name in the relNode can be avoided.
