Issue Title: Implement /translate Command

Issue Description: As a user of our Discord bot, I want to be able to use a "/translate" command to translate text from one language to another, so that I can communicate with users who speak different languages within Discord.

Feature Description:

• The "/translate" command should take two arguments: the source language and the target language, followed by the text to be translated.
• When invoked with the source language, target language, and text to be translated, the bot should fetch the translation from a translation API.
• The bot's response should include the translated text.

Acceptance Criteria:

• The "/translate" command is successfully implemented and tested.
• Invoking the "/translate" command with valid source language, target language, and text arguments should result in the bot fetching and displaying the translated text.
• The bot's response should include the translated text.

Additional Notes:

• This feature will provide users with a convenient way to communicate with users who speak different languages within Discord.
• Please ensure thorough testing of the "/translate" command functionality before closing this issue.
