Version 0.2.4

* Notifications now display errors and the output of the failed command.
* CI configs for GitHub and Woodpecker
* Added `version` subcommand
* Console logging can be disabled by setting `console-disabled` in the
`logging` object
* If Host was not defined for an incomplete `hosts` object, any commands
would fail as they could not look up the values in the SSH config files.
