Removed poetry and added pipenv

[rofrano]

Poetry was giving students a lot of problems with it's lock file, didn't play well in Dockerfiles, and the 2.0 version removed the shell command so I decided to just remove it in favor of pipenv which seems a lot easier to use.

Made the following changes:

• Create a Pipfile and Pipfile.lock for the project
• Move tool configurations from the pyproject.toml back to the setup.cfg file
• Removed the pyproject.toml, poetry.toml, and poetry.lock files from the project
• Updated the Devcontainer Dockerfile to use pipenv
• Updated the production Dockerfile to use pipenv
• Made some adjustments to the Makefile
• Updated the installed dev tools to the latest versions
• Removed Thunder Client from dev environment because it is not free anymore
• Removed Red Hat Analytics tools from dev environment because it kept giving Java errors and this is a Python environment (no Java)
• Updated the GitHub Action to remove poetry and use pipenv
