`:to_table` when adding a fk through `add_reference`.
Closes #21563. The `name` argument of `add_references` was both used to generate the column name `<name>_id` and as the target table for the foreign key `name.pluralize`. It's primary purpose is to define the column name. In cases where the `to_table` of the foreign key is different than the column name we should be able to specify it individually.
