Update ListenerMakeCommand.php (#19660)

* Update ListenerMakeCommand.php

Allow to make listeners for the events outside of App or Illuminate namespaces

* Update ListenerMakeCommand.php

Pass all prefixes to `Str::startWith()` in anonymous array. instead of calling it 3 times (even more useful if more prefixes will be added later on).

* Update ListenerMakeCommand.php

Typo :(
