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: #825

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

However this makes no sense for the rules introduced in: #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

doctor-rst/src/Formatter/ConsoleFormatter.php

Lines 92 to 94 in d16c1de

	if (!empty($violation->rawLine())) {
	$style->writeln(sprintf(' <info>-></info> %s', $violation->rawLine()));
	}
