Install openssh-client (Kaggle#971)

In Kaggle#967, I upgraded the base image from `m61` to `m64`.

The new  `m64` base image doesn't include a SSH client anymore.

This was causing issues with a learn course relying on `stable-baselines`. This package isn't included in our base image but is installed at runtime.
