Description

In the wazuh-password-tool.sh script, to change the password of an api user, it is necessary for the api user to specify the --api option. Failure to do so would result in the script's help being displayed.
To this end, a message has been added to the help in the -au and -ap options saying that it is necessary to specify the -A|--api option when using those options.
