no-extraneous-dependencies should allow specific whitelist

[Zamiell]

In some situations, packages are located at the monorepo root instead of in the closest "package.json" file.
In these situations, it would be useful to configure the "no-extraneous-dependencies" rule to have a whitelist of packages to not error on.

e.g.

  {
    rules: {
      "import-x/no-extraneous-dependencies": ["error", { whitelist: ["foo"] } ],
    },
  },
