Link to the page on docs.getdbt.com requiring updates

following up from pr #6615 -- we should remove the old image (/img/docs/dbt-cloud/using-dbt-cloud/prod-settings.jpg) since it's being replaced with the updated one?

note that /img/docs/dbt-cloud/using-dbt-cloud/prod-settings.jpg is used in another file too (dbt mesh quickstart) so that file should be updated with the new image too so there are not rendering issues.

also we have 3 image files conveying the same thing - do we want to consolidate so it's less maintenance?
