no-unused-disable does not work when turned on in a flat config

Just to add my use case here since I've seen the discussion in #133

It's possible to configure the severity globally with

export default [
    linterOptions: {
      reportUnusedDisableDirectives: 'off',
    },
    [...]
];

With a rule it would be possible to add a file matcher and apply it accordingly (what I would prefer).

Concrete use case: We generate api code via openapi generator, which includes the comments

/* tslint:disable */
/* eslint-disable */

I would like to exclude the directory of the generated code, but everything else should be marked depending of the configured severity(for example error).
