fix: add example for create_auth_claim & delete_auth_claim

[Subterrane]

This pull request adds functionality to manage authentication claims in sample_script.py. The new code demonstrates how to list authorization servers, create an authentication claim, verify its creation, and delete it, including error handling for each step.

Added functionality for managing authentication claims:

• Created an instance of APIAuthClaimsApi and APIAuthorizationServerApi to interact with authentication claims and authorization servers.
• Added logic to list available authorization servers, select the first server (if available), and create an authentication claim with a test configuration.
• Implemented functionality to list all authentication claims to verify the creation of a new claim.
• Added logic to delete the created authentication claim and verify its deletion by listing claims again.
• Included comprehensive error handling for all API interactions to ensure robustness.
