[FEATURE] Implement Localization for Discord Bot

[omgitsjan]

Is your feature request related to a problem? Please describe.
Users who speak languages other than English cannot fully utilize our Discord bot due to the lack of localization support. This hinders the bot's accessibility and usability for a wider range of users.

Describe the solution you'd like
Implement localization for the Discord bot, allowing users to change the bot's language via the appsettings.json file. This would involve:

1. Creating a folder containing language resource files (e.g., .json or .resx files) for each supported language, storing translated strings for bot responses and messages.
2. Updating the bot's code to fetch strings from the appropriate resource file based on the language setting in appsettings.json.
3. Providing documentation on how to add support for new languages or modify existing translations.

Describe alternatives you've considered
An alternative would be to integrate a third-party translation API, which would automatically translate bot responses to the user's desired language. However, this could lead to subpar translations and increased latency due to API calls.

Additional context
Localization would greatly improve the bot's accessibility to non-English speakers, thereby expanding its user base and promoting inclusivity.
