Redirect http to https

Almost all possible ways will redirect, except for http://www.dnd5eapi.co/
We can add a redirect, however, it is best to make sure this redirect only happens in deployed environments so it doesn't cause an issue with local development.

Look for environment configuration files and deployment scripts to understand how to differentiate between deployed and local environments. Check the server setup, likely using Express or a similar framework, to see where HTTP requests are handled. The goal is to add a conditional redirect for the specific URL http://www.dnd5eapi.co/ to HTTPS only in production.
