Hello,

ran into this on an older provider and didn't find a report. Docs say

The additional_ip_ranges_config block supports:

    [subnetwork](https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/container_cluster#subnetwork-2) - (Required) Name of the subnetwork. This can be the full path of the subnetwork or just the name.

However, with a cluster with location = <zone> it seems to fail with (a fairly cryptic since it's the cluster itself throwing the error)

Error: Cannot determine region: set in this resource, or set provider-level 'region' or 'zone'. 

if you provide google_compute_subnetwork.subnetname.name but seems to work fine with google_compute_subnetwork.subnetname.id.

Which is all fine and there's a seemingly understandable underlying reason so maybe it's easiest to just mention it in the docs?
