Add automatic deploy

[chand1012]

@RusseII and I agreed that it would be best if we had two branches to develop on - develop and master - that automatically deployed to AWS. That way while in production we don't have to deploy updates manually. The master branch would act as the production branch, with develop acting as a testing branch. Each developer working on the project would also have their own respective environments to test on. The stack will be deployed to AWS via GitHub Actions.
