Add Heroku deploy and frontend/backend deploy scripts

- Added local DB container
- Added scripts to deploy frontend/backend by running the deploy command in the containers
- Installing Docker and Heroku CLI in the dev backend container to be able to build and push the container without installing the CLI on the host
- Building and pushing the production container to the Heroku Container Registry
