feat: Add arguments for verbose output to installer script

[matherm-aboehm]

Description: When something went wrong without an error message or you just want to see what the installer script is actually doing, you want that this action adds -Verbose/--verbose arguments to the installer script. This PR solves this with a new action input parameter.
