Connect Communities page to backend GET api/v1/communities

[christopher-alba]

Currently the frontend and backend are unconnected
It would be great if you could connect the communities page to the backend to get all of the communities. There should already be a functioning frontend search so all you need to do is fetch the real data from the database.

The full Heroku GET endpoint you need to be hitting is https://uni-forum.herokuapp.com/api/v1/communities

Pre-requisites:

• completion of the GET communities endpoint in the backend (it's currently unimplemented)
• completion of seeding the MongoDB Atlas database automatically through a script which will create all of the communities you need to fetch

How to get started:

• use the axios "api" instance inside the api folder to make the api calls to the backend
