Continuation of the discussion in #4209 (comment)

• test: add more test consts #4209 (comment)

Mark the Randomizer interface properties as readonly.

export interface Randomizer {
  readonly next: () => number;
  readonly seed: (seed: number | number[]) => void;
}

I also considered only wrapping it inside FakerCore:

interface FakerCore {
  readonly: Readonly<Randomizer>;
}

Which variant should we use?

1. Randomizer with readonly properties
2. Readonly<Randomizer> in FakerCore

I prefer 1./the current variant, because it represents our expectation for the type and users can easily extend the type to be writeable. From writeable to readable you need to use explicit casts.

ToDo: Write migration guide after the variant has been chosen.
