fyi to @LRWeber about this change.

We may also want to delete requirements.txt since it references the other deleted file.

Our automated testing action currently has the dev dependencies hardcoded.

scraper/.github/workflows/main.yml

Lines 34 to 37 in 9593f4a

	pip install bandit black isort flake8
	pip install .
	npm install -g markdownlint-cli@0.33.0
	make test

Should it be using a different command to leverage the dependency list(s) in the .toml file (e.g. pip install .[dev])? Or is it specifically using a minimal list? (And if that's the case, should that be another list defined in the .toml file?)

@LRWeber - good catches! I just updated the actions file to convert over to using the definition out of the pyproject.toml file instead. Good catch!
