This adds the group columns in the results, even if they are not used.
If a group column is named aggregate, the DB engine will prefix it with the table name. We don't have conflict with the calculated aggregate.

I have fear this is going to be another breaking change 😅 any way we can be sure?

This doesn't affect queries created by the query builder. The result of the aggregate functions count, max... will stay the same (#53581).
It only add fields to the result when calling the grammar method directly. I moved the new columns last to keep the aggregate result first.
