Handler config fix

[axelsrz]

This pull request includes fixes to logging and configuration handling in the microsoft-agents-hosting-core library. The most important changes address a typo in a logger call and improve the robustness of authorization handler initialization.

Logging Fix:

• Corrected a typo in the logger call (ogger.error → logger.error) in the _on_error method of agent_application.py. This ensures proper logging of errors.

Configuration Handling Improvements:

• Fixed a typo in the variable name (handlers_congif → handlers_config) and improved the logic for initializing auth_handlers in authorization.py. The updated code ensures that auth_handlers is always initialized, even when no handlers are provided in the configuration.
