fix: add config options and error handling to MistralAI component (#6131)

* ✨ (mistral.py): Add new input parameters to MistralAIModelComponent for better customization and control over the Mistral model configuration
♻️ (mistral.py): Refactor build_model method to improve readability and maintainability by using try-except block for error handling and updating parameter names for better clarity

* [autofix.ci] apply automated fixes

* ♻️ (mistral.py): refactor MistralAIModelComponent class to improve code readability by formatting the IntInput and BoolInput sections for better organization and clarity.
