Replace deprecated 'request' library with a maintained alternative

[rohandhananjaya]

The current implementation of the chatbot backend uses the request library for HTTP calls. However, the request library has been deprecated and is no longer maintained. This could lead to potential security vulnerabilities and lack of updates in the future.

Steps to Reproduce:

• Navigate to the /rawbot endpoint.
• Observe the usage of the request function for making HTTP calls.
• Expected Behavior:
• The backend should use a maintained and actively supported library for HTTP requests.

Actual Behavior:

• The backend uses the deprecated request library.

Suggested Fix:

• Replace the request library with a more modern and maintained alternative, such as axios or node-fetch.
