Update Django CI/CD GitHub action for Docker/Postgres/Gunicorn/Nginx deployment structure

[jaw12346]

Our CI/CD action for Django no longer works due to the addition of Docker and Postgres. We need to implement a new GitHub action that can test our code using this new deployment structure.

This has to be manually written.Things to do:
1.set up django(repo)
2.setup gunicorn server(still an easy one)
3.set up nginx(SSL-disabled version maybe)
4.Create a shell script to initialize the whole project.
5.create docker with shell script above.
