The description and error messages are outdated and are legacy of the command originally being named "approve". Change them to be more appropriate to the current usage of the command, which is to apply reviews, which may or may not include approvals, to patch sets. Also rename the `approveOne` method to something more appropriate. Change-Id: If95a24b8998bbac9a2ea410ecc05974674070e06
