Create Bot Translation System and Language Files

🌍 Feature: Create Bot Translation System and Language Files

📋 Description

This issue aims to implement the multilingual support system for SalemBot by creating structured translation files and replacing hardcoded strings with dynamic, locale-aware alternatives.

---

✅ Goals

• Provide support for multiple languages in the bot (starting with French and English).
• Centralize all user-facing text in translation files.
• Create a helper utility to fetch strings based on the user's language or server default.

---

📁 File Structure

Translation files will be stored in: src/data/lang/

Each language should have its own JSON file:

• fr_FR.json
• us_EN.json

---

🛠️ Implementation

• Create a get_translation(key: str, lang: str = "us_EN") utility that fetches a localized string.
• Add support for pluralization and dynamic variables (e.g., "Welcome, {username}!").
• Replace all hardcoded user-facing strings (e.g., "Meow...", "Welcome", etc.) with dynamic translations.
• Default to English (us_EN) if translation key or locale is missing.
• Automatically detect language based on Discord server region or user preference.
• Include a /language command to allow players to change their language settings.
