Pull Request Overview

This PR adds a comprehensive example demonstrating transient compressible flow simulation in PyFluent. The example simulates airflow through a nozzle with time-varying boundary conditions, showcasing steady-to-transient coupling, dynamic boundary conditions, and adaptive meshing for high-speed flows.

Key changes:

• Adds a new transient compressible nozzle workflow example with complete meshing and solver setup
• Integrates the example into documentation build configuration and CI/CD workflow
• Includes changelog entry documenting the new feature
