…rm scope for default credentials (googleapis#3376)

## Description

This PR specifies the `cloud-platform` OAuth2 scope when finding default
Google Cloud credentials for the Dataplex and Datalineage connections.

Without this scope, connection initialization can fail with
authorization issues under Application Default Credentials (ADC) if the
default scopes lack access to Dataplex or Data Lineage APIs.
