Removed repeated line of text. (#4479)

## What are you changing in this pull request and why?

I have removed the repetition of the line _'Do the column names and

**'Structuring'**.

It doesn't look to me like the above line was repeated for emphasis. I
think it looks like a possible mistake?

 If your data is not in a format that is usable, you can look into different solutions such as pivoting or using different functions to unpack lists and JSON files so that they are in a tabular format. Pivoting is helpful because it allows you to change the way your dataset is structured by rearranging the way columns, rows, and their values are displayed. dbt has a [pre-built macro](https://github.com/dbt-labs/dbt-utils/blob/main/macros/sql/pivot.sql) that makes pivoting less of a headache and more of a breeze.
