Hey team, I was looking to use the google ads hook but it seems like the google ads package is a bit out of date with the hook only taking "v5", "v4", "v3", "v2" https://developers.google.com/google-ads/api/docs/release-notes and all of those being deprecated.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

```

When installing providers from sources we install all namespace packages found below airflow,
        including airflow and provider packages, otherwise defaults from setup.cfg control this.
        The kwargs in setup() call override those that are specified in setup.cfg.
