Installation with `pip==23.1` gives PyYAML error

The newest version of pip produces unstable results, e.g., sagemaker-ssh-helper may fail to install in some SageMaker Studio kernels with the following error:

```
ERROR: Cannot uninstall ‘PyYAML’
```

The current workaround is to downgrade pip to the previous version:

```
pip install pip=23.0.1
```
