Automated Deployment Workflow

* Test workflow to SSH into EC2

* Dockerfile to containerize frontend

* Update workflow to build docker image and run container

* Deploy to different locations based on branch

* Use proper reference to environment variables

* Revert to singular Dockerfile

* Remove unused environment var from dockerfile

* Remove old docker image before building new one

* Test with real dev site

* Swap ports of dev and prod

* Add nextauth to env of container

* Write secret directly to env file

* Echo newline into env file

* Take secret part out - that doesn't need to happen every deploy

* Add main branch to workflow
