Support for Cloud SQL Query Insights

Describe the feature or the resource that you want.

Context: see #386

Cloud SQL for PostgreSQL recently added a feature known as Query Insights. The API docs for SQLInstance don't yet document how to configure this feature via the API, but the API presumably exposes a settings.insightsConfig field based on the sample request body on this page.

The upstream changes have been made - what needs to be done to import the changes here?

Hi @ve6yeq, now that Terraform released the feature as part of their v3.58.0 release, it should be brought over to Config Connector once we upgrade our Terraform dependency. This means that, assuming there are no issues with the dependency upgrade, the feature should come out on Config Connector within the next couple of releases.

In v1.41.0, insightsConfig field is supported in SQLInstance.
