GitHub App support for Enterprise Copilot seat management

GitHub added support for enterprise GitHub Apps to manage Copilot seats. An enterprise-owned App can now call the enterprise-level Copilot seat management APIs to control which users and enterprise teams are assigned Copilot seats.

Access comes through a new enterprise fine-grained permission for Apps, called Enterprise Copilot license management. Grant that permission to the App and it can use the seat management APIs.
