Describe the bug

This code produces base last names:

import { fakerRU as faker } from "@faker-js/faker";

console.log(faker.person.lastName());

Expected: this code produces localizated last names

Minimal reproduction code

https://codesandbox.io/p/sandbox/faker-js-ru-not-working-forked-cthnpl?file=%2Fsrc%2Findex.ts%3A20%2C41

import { fakerRU, ru as localization } from "@faker-js/faker";

//THIS TEMP FIX:
// import { base, ru, Faker } from "@faker-js/faker";

// const customFaker = new Faker({
//   locale: [ru, base],
// });

const faker = fakerRU;

let maxIterations = 1000;
let found = false;
let i = 0;

console.log(localization);

const allLastNames = [
  ...localization.person.female_last_name,
  ...localization.person.male_last_name,
];

console.log(allLastNames);

while (!found && i++ < maxIterations) {
  const text = faker.person.lastName();

  console.log(text);

  found = allLastNames.some((t) => t === text);

  if (found) {
    console.log("Found", text);
    break;
  }
}

if (!found) console.log("Not found");

Potential dublicate of #1677

• Change file structure for gendered lists (names, prefixes etc) #1677

This affects locales that have a male_last_name and female_last_name file but no last_name file.

Specifically:

sk
id_ID
lv
ru
uk
az
uz_UZ_latin

We can solve this by adding a last_name.ts file with mergeArrays. This is already done for these locales:

cs_CZ
dv
mk
