This PR updates Govultr to support the new API properties associated with the FerretDB offering for Vultr Managed Databases. The API docs already support "ferretpg" as a valid engine type upon launch, but the database results need to support to ferretdb_credentials object (and associated connection info) now returned from the API for those subscription types.
