Specify driver dependencies for particular databases in the documentation

[zaleslaw]

The page doesn't contain any information about setting up of driver dependency on a particular database to set up it properly.

Comments from @Jolanrensen

Actually, not even sure what's going on here.
Neither USE { dependencies("org.postgresql:postgresql:42.6.0") }
nor @file:DependsOn("org.postgresql:postgresql:42.6.0")
works...
I can only get it to work by using the "Select Project Libraries to add to the Notebook Classpath" setting and adding PostgreSQL as a dependency to that project. That can't be the proper way to do it.
