Cloud DNS API Client Library v2 misses GCP API 2.0 support

https://github.com/googleapis/google-api-java-client-services/tree/main/clients/google-api-services-dns

**Is your feature request related to a problem? Please describe.**
I tried to update all my existing Dependencies to match with Google API 2.0, unfortunately there is no possibility to update the [v2](https://github.com/googleapis/google-api-java-client-services/tree/main/clients/google-api-services-dns/v2), because support for 2.0.0 is missing. So at the moment I switched to [Cloud DNS API Client Library v1](https://github.com/googleapis/google-api-java-client-services/tree/main/clients/google-api-services-dns/v1/2.0.0) to find a supported version

**Describe the solution you'd like**
Support Google API 2.0 with Cloud DNS API Client Library v2 pls.
