[feat]: Improving bot.js for faster responses, and have enhanced error handling

[Yash-Vashishth]

Hi @jinx-vi-0 !! Your bot design is amazing !! Though it is concise I think it needs a lot of changes to function in a refined manner.

Here is a summary of the changes I will make- better code organization, enhanced error handling, modular functions for different command handlers, and improved readability.

A long and boring form:-
1.Separate Concerns: Split large functions into smaller, more manageable ones. For instance, the messageCreate event handler could be broken down into separate handlers for each command.
2. Modularization: Create separate files or modules for different functionalities like command handling, utility functions, etc.
3. Cache frequently used data to reduce API calls and improve response times.
4. Optimize the fetchLeetCodeProblems function to handle large datasets efficiently.
5. Follow consistent naming conventions and code formatting for better readability.
6. Using ESLint or Prettier to enforce consistent coding standards.
