Code Review

This pull request introduces a 'hello world' test for Azure by adding the necessary configuration files and a new test variation. The overall structure is correct, but there is a critical security vulnerability due to hardcoded secrets in the release/ray_release/environments/azure.env file. These sensitive values must be removed from the repository and managed through a secure secrets management system.

Hardcoding secrets and sensitive identifiers in source code is a major security risk. This file contains sensitive values such as RELEASE_AWS_ANYSCALE_SECRET_ARN, RELEASE_DEFAULT_CLOUD_ID, and RELEASE_DEFAULT_PROJECT. These values should be removed from the repository and managed through a secure mechanism, such as CI/CD environment variables or a secret management service like AWS Secrets Manager. The values can then be injected into the test environment at runtime.
