The requirements install uses pip install -r requirements.txt instead of python -m pip install -r requirements.txt. With a version matrix, calling pip directly can target a different interpreter than the one set up by actions/setup-python, leading to hard-to-debug CI failures.

Suggested change

	if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
	if [ -f requirements.txt ]; then python -m pip install -r requirements.txt; fi
