Issue description
Using ipython magic-action %%script to call modular's magic shell gives an error (see steps to reproduce).
Steps to reproduce
Using ipython magic-action %%script to call modular's magic shell,
while offline,
running a no-op comment line of #,
I get the following error:
Error starting shell: Not a tty (os error 25)

313 rc = p.returncode or -9
--> 314 raise CalledProcessError(rc, cell)
CalledProcessError: Command 'b'#\n'' returned non-zero exit status 1.
The following works just fine: %%bash, %%python, %%script bash, %%script python.
Reproducible in notebook: https://www.kaggle.com/code/michaeldgibson/offline-mojo-template/notebook?scriptVersionId=194491514
After calling %alias_magic --cell mojo script -p 'magic shell', new notebook cells can start with %%mojo which should compile the cell for mojo once these errors are able to be fixed.
