fix(greenhouse): ensure nginx redirects to /index.html for unknown routes

[taymoor89]

Summary

This PR fixes the issue where when(greenhouse is) served via nginx web server client side routes like /doop, /heureka do not work because these are unknown to the web server. So in case of unknown routes we need to serve /index.html so the client side router takes over the responsibility to render the correct page.

• Changed nginx.conf

Testing Instructions

Most efficient way is to test it directly on QA after merge otherwise need to spin up nginx on local server with these configuration and verify it that works.
