RFR: 8356128: Correct documentation for --linux-package-deps [v3]

[Stefan Lobbenmeier]

> The documentation suggests that --linux-package-deps is a boolean option, while in fact it is a string option with dependencies separated by comma and space
> 
> You can tell that this option is supposed to have an argument here: https://github.com/openjdk/jdk/blob/fea5f2b1458cdd53f437e59caaffaa6e22fb59a7/src/jdk.jpackage/linux/classes/jdk/jpackage/internal/LinuxPackageBundler.java#L366-L372
