Updated Dockerfile and docker-compose.yml

[nkarl]

The container config is severely outdated. I have updated the following:

1. pulled many dependencies out of Dockerfile and moved them to docker-compose as environment variables.
   • This helps with dependency management for future courses.
2. updated as many dependencies as possible with respect to regression.
   • I didn't want to deviate too much from the 4th iteration. As I work through the Plutus Pioneer Program I am not yet at the level to know which pinned packages in cabal.project are safe to update.
3. organized the Dockerfile to build more smoothly in VSCode.
   • for example, it makes little sense to run cabal commands in the middle of pulling the dependencies. These commands should be left to the users/students when they begin Week 02 of the course.
