Lint/Syntax is able to be disabled by directive comments

[Earlopain]

Consider this very simple example file:

foo*

This isn't valid syntax and RuboCop complains. If I change this snippet to the following no offense is detected anymore:

# rubocop:disable Lint/Syntax
foo*

My understanding is that Lint/Syntax should not be able to be disabled under any circumstance. https://docs.rubocop.org/rubocop/1.60/configuration.html

The cop enabling process can be altered by setting DisabledByDefault or EnabledByDefault (but not both) to true. These settings override the default for all cops to disabled or enabled, except Lint/Syntax which is always enabled, regardless of the cops' default values (whether enabled, disabled or pending).

There is one exception from the general rule above and that is Lint/Syntax, a special cop that checks for syntax errors before the other cops are invoked. It cannot be disabled and its severity (fatal) cannot be changed in configuration.

If this is considered a bug then RedundantCopDisableDirective and RedundantCopEnableDirective should probably detect this as an offense. (actually, probably not? It's not valid syntax after all, don't think that would work)
