install pymc in the recommended manner for remote workflows

[drbenvincent]

Following a discussion with @ricardoV94, it seems that we are pip installing pymc. We should instead install pymc in the recommended manner.

I'm not 100% sure how to implement this currently, but I'm assuming we need to edit files in .github/workflows. Perhaps...

CausalPy/.github/workflows/ci.yml

Line 43 in 83cb28c

pip install -e .[test]

which may well require changes to the pyproject.toml file

CausalPy/pyproject.toml

Lines 29 to 43 in 83cb28c

	dependencies = [
	"arviz>=0.14.0",

Is this something that @maresb might have expertise with?
