Include warning in docs about polymorphism in underlying tables
We had a bug whereby we changed the namespace on a model using ActiveStorage, which resulted in broken download links. The reason this happened is because the `active_storage_attachments` table is a polymorphic join table that records the model's class name at the time of record creation, and uses this `record_type` in queries. Since the model namespace changed, the queries did not return the blob as expected. Discussed with @rafaelfranca, who suggested adding a warning about this in the docs.
