Issue:
Adding a comment to an `AUDIT` sql file fails to load it
Adding a comment to an `AUDIT` sql file:

```sql
-- Some comment
AUDIT (
  name assert_order_items_quantity_exceeds_threshold
);

SELECT *
FROM @this_model
WHERE quantity <= @quantity
```

Will fail to load it with the following error:

```
Error: Invalid extra fields {'description'} in the audit definition at 'examples/sushi/audits/order_items.sql'
```

Pull request description:
Fix: allow comments in audit file
Currently, the audit loader assigns any SQL comments above the audit DDL to the audit's `description` field. That field does not have first-class support, so audits with a comment present errored out.

This PR allows comments to be present by removing the assignment of the comment to the description field.

Closes #2054
