Pyright static analysis doesn't propagate fully to Python Quarto cell

[jackkrebsbach]

Bug description

Not all of Pyright's static code analysis propagates to Quarto Python cells. In particular, we do not get warnings for undefined variables. This seems to not happen in Python files themselves. In the example below I would expect the same error of an undefined variable as I see in the Python file.
