Adopt upstream version scheme

[jlaine]

First of all thanks for providing this library, it's still the most convenient way to install libphonenumber out there!

Since what this package provides is an unmodified version of the upstream library, wouldn't it make sense to just use the same version number?

This would make it much easier to track which upstream version you are providing. It is also the approach taken by the Python version of libphonenumber: https://github.com/daviddrysdale/python-phonenumbers

I think this makes sense. I don't see an immediate problem with upgrading from v3 (current) to v8.

Cool! Once you make this change, I'd be happy to provide a PR for an automated GitHub action which periodically checks whether the local version matches the upstream version so you don't need to monitor the libphonenumber mailing list.

I did the same for the Python package: daviddrysdale/python-phonenumbers#275

Hi @ruimarinho I hope you are well? Have you given any additional thought to my suggestion of adopting the upstream numbering?
