Fix Vietnamese numeral reading and optimize configuration (#51)

* Handle large number groups in Vietnamese numeral reading

Updated logic to repeat "tỷ" based on group position dynamically, ensuring accurate representation for billions, octillions, and undecillions. Added comprehensive test cases to validate the new functionality and edge cases.

* Simplified `readVnNumber` string conversion for improved readability

* Adjust changeset config and package workspaces for docs

Updated changeset configuration to ignore the `docs` directory, preventing unnecessary change tracking. Added `.` as a workspace in `package.json` to ensure proper package management.

* Fix billion suffix logic and use new Array()
