Description

Feature description

In the micronaut-langchain4j-vertexai-gemini module, if the application is already using Micronaut's GCP support, it would be really convenient if the Vertex integration utilized the GoogleCredentials created by the defaultGoogleCredentials() method which has a very nice algorithm for creating the credentials most applicable.

Contributor guide

Research direction
Investigate how to import and use Micronaut's `GoogleCredentials` via the `defaultGoogleCredentials()` method in the `micronaut langchain4j vertexai gemini` module. Look at the existing GCP support integration and modify the Vertex AI configuration to use these credentials instead of manual creation.
