Cowsay-donatello

Hey everyone,

To satisfy user demand for a cow that doesn't talk too much, I've installed the `cowsay` package on **donatello (192.168.42.182)** from the Debian repositories, along with the `censored-cow` cowfile for a cow without an explicit udder.

The installation uses minimal disk space on the OS root drive, RAM, and CPU resources.

The cow itself requires no network bandwidth or dedicated network interface, although the service is accessible via **https://192.168.42.182**.

This is an additional installation alongside the existing cow on leonardo.
