How to deploy new world-server code.

1.) Make sure your dialog repo changes are commited to the dialog/worlds branch.

2.) Go to world-server repo and bump the package.json version number. (this triggers the GH action to execute and create a new release, it will pull dialog/worlds)

3.) After the GH action is done, copy the hash of the release and paste it into exokit-backend/routes/worlds.js in the updateZipFile() fetch url.

4.) SSH into exokit-backend EC2 server (can get the IP from AWS dashboard), and delete the world-server.zip file. (it exists inside ~/exokit-backend/)

5.) npm run start inside of exokit-backend. (this will start a forever process and start downloading the new ZIP file from the Github release.

6.) After it is done, verify the logs. (sudo forever list, sudo forever logs [index]) The server is up and running and will create new world-servers with the fresh codebase.

P.S. To truly wipe the old servers and start fresh, you need to login to AWS and terminate the old world servers OR you can use the DELETE API for worlds.
