Description

Hi team,
when running the second to last cell in the Jupyter Notebook 01_GettingStartedwithSentineldatalake.ipynb, an error regarding the "System Tables" value is returned.

    data_provider.save_as_table(
            df_recent_raw,
            output_data_lake_table,
            "System tables",        # System tables refers to writing to data lake tier table.
            write_options
        )
    print(f"✅ Wrote test data into {output_data_lake_table}")
except Exception as save_err:
    print(f"❌ Failed writing data into {output_data_lake_table}: {save_err}")

Error output:
{"level": "ERROR", "run_id": "446edae9-6d04-49c2-b7e5-7168dffbfb29", "message": "Database Name System tables doesnt exist."} ❌ Failed writing data into Test_output_table_SPRK: Database Name System tables doesnt exist.

Steps to reproduce: Run the above cell in order after executing the previous cells in the notebook.
