Importing sagemaker seems to enable rich tracebacks

**Describe the bug**

Whenever sagemaker is imported, it seems to modify and automatically enable [rich](https://github.com/Textualize/rich) tracebacks.

**To reproduce**

Make a new environment

```console
$ python -m venv .venv
$ source /.venv/bin/activate
$ python -m pip install sagemaker rich
```

Make a file that returns a traceback

```python
"""rich_sage.py"""
import sagemaker

def main() -> None:
raise ValueError

if __name__ == "__main__":
main()

```

Run the file

```console
$ python rich_sage.py
sagemaker.config INFO - Not applying SDK defaults from location: /Library/Application Support/sagemaker/config.yaml
sagemaker.config INFO - Not applying SDK defaults from location: /Users/pawlu/Library/Application Support/sagemaker/config.yaml
╭─────────────────────────────── Traceback (most recent call last) ────────────────────────────────╮
│ /Users/pawlu/Documents/scratch/rich_sage/sage_me.py:9 in │
│ │
│ 6 │
│ 7 │
│ 8 if __name__ == "__main__": │
│ ❱ 9 │ main() │
│ 10 │
│ │
│ /Users/pawlu/Documents/scratch/rich_sage/sage_me.py:5 in main │
│ │
│ 2 │
│ 3 │
│ 4 def main() -> None: │
│ ❱ 5 │ raise ValueError │
│ 6 │
│ 7 │
│ 8 if __name__ == "__main__": │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
ValueError
```

If the import statement is removed,

```diff
- import sagemaker
```

then the traceback renders as expected

```console
$ python rich_sage.py
Traceback (most recent call last):
File "/Users/pawlu/Documents/scratch/rich_sage/sage_me.py", line 8, in
main()
File "/Users/pawlu/Documents/scratch/rich_sage/sage_me.py", line 4, in main
raise ValueError
ValueError
```

**Expected behavior**

Ideally, tracebacks shouldn't be modified without users input. At worst there should be a way to opt out of this. But we shouldn't be modifying tracebacks automatically at import. It's a tricky behavior that's hard to debug.

Thank you very much!

Esegui la riproduzione in rich_sage.py con le versioni indicate di SageMaker e Rich, confrontando l’output del traceback con e senza import sagemaker. Traccia l’effetto collaterale dell’importazione nel pacchetto SageMaker e verifica che importarlo non abiliti più i traceback arricchiti di Rich senza l’intervento dell’utente.
