Fix echo/base64 examples commands

[gouglhupf]

Change Overview

The commands to create base64 encoded strings for manual secret creation are wrong. The echo command prints a new line by default. This alters the actual value to be encoded.

To keep this from happening you can add the parameter -n or use the command printf.

echo "YOUR_KEY" | base64 returns WU9VUl9LRVkK and
echo -n "YOUR_KEY" | base64 returns WU9VUl9LRVk=.

The Kubernetes documentation also suggests the echo -n command. https://kubernetes.io/docs/concepts/configuration/secret/#creating-a-secret-manually
