Add argentina zipcodes

[Jonathan-Zollinger]

Overview

replaces the current 4-digit generator with an exhaustive list of argentine zip codes. I also noted that es-AR wasn't included in the list of locales in the README, so I added it there.

Points to consider

Argentine zip codes preface 4 digits with an iso code as a single letter (ie A####). This PR includes the appropriate iso code with the zip code such that each zip code provided is an actual zip code used in argentina. These can be found at https://postalcodes.azinfoportal.com/argentina/

Test coverage

I added a new test which iterates through all 4025 new zip codes and validates that they're all formatted with an expected letter followed by 4 digits. I'm not sure how much more to test than that.

calling ./mvnw clean install from root runs w/ no errors.

PR Summary

• Updated Documentation
  • The README.md file has been modified to include support for Argentine language settings. This means that the project can now run seamlessly for users interacting with the system in that language.
• Improvements in test coverage
  • The changes in 'AddressTest.java' involve a new method that helps test Argentine zip codes more effectively, ensuring correct format for these codes. This implies more comprehensive test coverage, enhancing the reliability of the system for Argentine users.

Not related to this PR perhaps, but is this comment still relevant? If so, I don't get it :)

@Jonathan-Zollinger @bodiam Things like postcode: should be located in file _AR.yml, not es_AR.yml. Postcodes are country-specific and don't depend on language.

In other words, postcodes would be the same for new Locale("es", "AR") and new Locale("en", "AR").

[Jonathan-Zollinger]

that makes sense. I can move those changes and update the tests
