Subject: [PATCH] fix: optional args on faker.finance.iban()

`faker.finance.iban()` is a valid use of Faker. However in TypeScript you get a type error because the optional `formatted` and `countryCode` args are not marked as optional like in other functions.

Tests are written against the cjs bundle without types so did not catch the error.
