docs: Create a new {@link ListRandomizer} that will generate a list with a fixed number of elements.
  Each element is generated by the {@link Randomizer} parameter
  
  @param elementRandomizer The {@link Randomizer} used to generate each element
  @param <T>               the type of elements generated by the randomizer
  @param nbElements        The number of elements to generate
  @return a new {@link ListRandomizer}
