fix(cmd): Change tense for deletion of active context (#1412)

"You are deleting" implies that I can abort the action somehow. In other
user interfaces, it's common to end sentences like this with "Are you
sure?". Given that the hcloud CLI doesn't do this and happily deletes
the context, I changed the wording to indicate that the action was
executed.
