Review Comment:
   Tables can be created using LIKE  in 
   1. Flink Catalog - Not supported currently.
   2. Another table in Iceberg catalog itself as detailed in 
[doc](https://iceberg.apache.org/docs/nightly/flink-ddl/#create-table-like)
   
   This check basically fails, if we try to create table using LIKE in Iceberg 
catalog, basically case#2 if we have **connector=iceberg** in options.
   
   In order to support Case#1 without user setting any extra Options using WITH 
clause, we need to add connector in getTable,

   This check was added in very old PR, 
   https://github.com/apache/iceberg/pull/2666 
   https://github.com/apache/iceberg/pull/2666#discussion_r660569612 where 
Flink SQL didn't support CREATE TABLE A LIKE B , where A and B are in different 
Catalogs.
