cli/command/volume: remove example and var for long description

This was the only command for which we set the "example" field; while
we could consider doing this for other commands, we need to look what's
best w.r.t. duplicating the information maintained in markdown.

Also remove the intermediate variable used for the long description,
as this was also the only location where we used one.
