[TPC-DS] Schema mismatch vs TPC spec #437

Some TPCDS column names do not match the TPC spec: https://www.tpc.org/TPC_Documents_Current_Versions/pdf/[TPC-DS_v4.0.0.pdf](https://www.tpc.org/TPC_Documents_Current_Versions/pdf/TPC-DS_v4.0.0.pdf)

The following deviate:

• cr_return_amount_inc_tax instead of cr_return_amt_inc_tax
• ib_income_band_id instead of ib_income_band_sk
• r_reason_description instead of r_reason_desc
• s_tax_precentage instead s_tax_percentage correction
• wr_store_credit instead of wr_account_credit

Java/C implementations had these typos, wouldn't it be better to adhere to the official TPC spec?

In LakeBench we made a strategic decision to adhere to spec so I'm currently evaluating whether we should intentionally adopt the typos just so that we can leverage this amazing project. We previously did not as the DuckDB generator did follow the spec without typos and this is what we elected to use for data generation.
