Remove non-existant subnetIds field from `TestIgnoringScalingChange…

…s` (#1602)

### Proposed changes

Fixes the `TestIgnoringScalingChanges`. Previously, the following `
Object literal may only specify known properties, and 'subnetIds' does
not exist in type 'NodeGroupV2Args'.` error occurs when running the
upgrade test.

### Related issues (optional)

Fixes: #1601
