Hey team, I was looking to use the google ads hook but it seems like the google ads package is a bit out of date with the hook only taking "v5", "v4", "v3", "v2" https://developers.google.com/google-ads/api/docs/release-notes and all of those being deprecated. Is there any chance the provider can be upgraded to include this? here is the release note of https://github.com/googleads/google-ads-python/releases/tag/12.0.0 google's 12.0.0 release which also deprecated v5


**Apache Airflow version**:  2.0.1


**What happened**:
 deprecated API endpoint, need to update google ads to version 12.0.0

**What you expected to happen**: 
return query data, instead, I get an error returned from the google ads v5 API:


**How to reproduce it**:
 attempt to hit the v5 API endpoint



**Anything else we need to know**:
 error is below

```
