Can't override non-observables in finnish with strict enabled

[TheKoTech]

If strict is true, there is no way of allowing $ postfix for non-observables

'rxjs/finnish': [
  'error',
  {
    strict: true,
    names: {
      '^(IS_MOBILE_MODE)': true,
    },
  },
],

// Error: Finnish notation should not be used here.
export const IS_MOBILE_MODE$ = new InjectionToken<Observable<boolean>>('IS_MOBILE_MODE$',  { ... });
