A rule or rule type should be able to configure if the content of the line is shown

[OskarStark]

Maybe this should be implemented after: https://github.com/OskarStark/doctor-rst/issues/825

Currently we show the line content for all rules/types:

However this makes no sense for the rules introduced in: https://github.com/OskarStark/doctor-rst/pull/824

We should use Line number 0 like now to be able to annotate on Github, but showing the content of this line 0 is confusing.

I think is now possible with the Violation object. When rawLine is empty line is not displayed
