Officially support Python 3.12 and 3.13

**Describe the feature you'd like**

I'd like to see official guarantees that this Python package runs under Python 3.12 and 3.13, which were released on 2023-10-02 and 2024-10-07 respectively. I can only see support for Python 3.11 in [`pyproject.toml`](https://github.com/aws/sagemaker-python-sdk/blob/8a559adde94689590320203c41ac5a49cd17185e/pyproject.toml#L31).

**How would this feature be used? Please describe.**

Ensure I can move my own code to Python 3.12 and 3.13 and benefit from the features from these releases.

**Describe alternatives you've considered**

Using the sdk although it's not officially supported with Python 3.12 und 3.13 and YOLO. 😀

Comienza con la declaración de la versión de Python compatible en pyproject.toml, en la línea 31, y luego inspecciona la configuración del repositorio para determinar dónde se prueba o se garantiza la compatibilidad. Se considera terminado cuando Python 3.12 y 3.13 estén incluidos oficialmente y las comprobaciones de compatibilidad del paquete pasen en ambas versiones.
