Repro Code

type ErrorTypes = NotKnown | 0;

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-redundant-type-constituents": "error"
  }
}

tsconfig

{
  "compilerOptions": {
    // ...
  }
}

Expected Result

The error message shouldn't phrase the NotKnown as "any", since it's really an "error" type. It's confusing to have it mentioned as any.

Actual Result

'any' overrides all other types in this union type. 1:19 - 1:27

Split out of #8304 <- #8231.
