We need a small documentation update for breaking API changes here:

https://www.zabbix.com/documentation/current/en/manual/api/changes_6.0_-_6.2

configuration.import "groups" no longer works in favor of "host_groups" and "template_groups". The page only specifies configuration.export.

This is minor, but for my integration, I initially missed it since I scroll through these documents when I update to new versions.
