Feature: Add and implement i18n translation locales.

[mayan-000]

Description

This PR implements the i18n getMessage function across strings whose translations are available.

• Implements getMessage and getFormattedMessage functions for extracting required text for a key from JSON files.

Relevant Technical Choices

• The translations are available till v0.7 of the repository, due to this if any text was added/modified after that, it must be visible in English only.
• Adds a -l --locale flag to prompt users for the locale they want.
• Supported locales: en[default], hi, es, ja, ko, pt-BR

Testing Instructions

• Change the system language to supported locale.
• Open extension in new instance of Chrome and open PSAT.
• The UI should contain texts translated to selected locale.
• Now open terminal, and run cli with flag -l.
• The generated dashboard should be in passed on locale.
