[Fusion] Redshift's helper macro `render_from_context()` fails because of Pythonic Jinja

[dataders]

Fusion is failing (understandably) on this line that uses *varargs and **kwargs. with the below message. I don't even know what the context var is doing here.

{{ return(package_context[name](*varargs, **kwargs)) }}
