The backup pages do not mention free plan

[TibsAtWork]

What should we add to our content collections?

The Aiven free plan services are well documented at https://docs.aiven.io/docs/platform/concepts/free-plan

That page mentions backups. When I go to specific backup pages, for instance https://docs.aiven.io/docs/platform/concepts/service_backups and https://docs.aiven.io/docs/products/postgresql/concepts/pg-backups, there is no mention of the free plans.
