[component] Google Analytics

As a Workflow Developer,
I want to be able to use the native **Google Analytics** connector,
So that I can implement more complex integration use cases involving **Google Analytics**.

**Reference**

- Website: https://marketingplatform.google.com/about/analytics/

- Documentation: https://developers.google.com/analytics/devguides/reporting/data/v1

**Acceptance Criteria**

Implemented actions:

- [ ] create expanded data set
- [ ] get account
- [ ] list accounts
- [ ] list audiences

**Definition of Done**

Start with the linked Google Analytics Data API documentation and identify how its account and audience operations map to the four requested actions. Done means all listed actions work, unit or integration tests pass, connection setup steps and a Guidejar tutorial exist, and generated documentation is available.
