Adjust KPT LZ instructions for solutions/core-landing-zone/0.2.0 not core-landing-zone@DEV

I know these are going through a retrofit - but the kpt versions need to be adjusted from DEV/PROD...

https://github.com/GoogleCloudPlatform/pubsec-declarative-toolkit/tree/main/docs/landing-zone-v2#fetch-the-packages

use landing-zone-v2 over landing-zone
* [new tag] solutions/core-landing-zone/0.2.0 -> solutions/core-landing-zone/0.2.0
