[Bug]: Fix linting action

[glsdown]

Overview

Currently there are inconsistencies in the SQL scripts styles used (e.g. trailing vs leading commas). It's unclear if this is because the check was ignored when the files were amended, or if the check isn't working.

How to reproduce

• Example leading commas - models/dim_dbt__current_models.sql
• Example trailing commas - models/staging/stg_dbt__models.sql

Expected behaviour

All files to have consistent formatting.

I can see the inconsistencies. I propose a giant PR that switches everything to leading commas. I'd be up for it!
