Update Vietnamese numeral reading and optimize configuration

[hckhanh]

Description

This pull request includes the following changes:

1. Adjust changeset config and package workspaces:

   • Updated the changeset configuration to ignore the docs directory, preventing unnecessary change tracking.
   • Added . as a workspace in package.json for better package management.

2. Improve readability of readVnNumber function:

   • Simplified string conversion logic, enhancing code clarity and maintainability.

3. Handle large numeral groups in Vietnamese numeral logic:

   • Enhanced logic to repeat "tỷ" based on group position dynamically, ensuring accurate representation for large numbers such as billions, octillions, and undecillions.
   • Added new test cases to verify the updates and cover edge scenarios.

Checklist

• I have written necessary tests for my code.
• I have updated the documentation where relevant.

Pull Request Overview

This PR enhances support for very large numbers in Vietnamese number reading by dynamically repeating "tỷ" based on group position, and simplifies the string conversion logic in readVnNumber.

• Updated getUnitSuffix to dynamically generate repeated "tỷ" suffixes based on position (e.g., "tỷ tỷ tỷ" for octillions)
• Simplified string conversion in readVnNumber from number.toString() to '' + number
• Added test coverage for octillions and undecillions
