Need to create a public route '/about' with static back-end info response

[deb2000-sudo]

Feature request:

Our application requires a publicly accessible route at /about.

Acceptance criteria:

• Add a new API route /about on the backend.
• The response from /about should be:

  This is all about backend
  

• No authentication required for accessing this route.
• Response should be in plain text.

Purpose:
This route will be used for general information about the backend, accessible by anyone.

Notes:

• Follow existing route conventions in the project.
• Ensure appropriate tests are added.
• Note to Contributors: Please comment "I'd like to work on this" if you are interested, and I will assign it to you.
