Permission denied looking for pyproject.toml

Describe the bug

I have marimo==0.16.5 (but the problem appears also in earlier versions) on osxaarch64.

Any attempt to run any notebook causes:

marimotest aszek$ python3 notebook.py 
Traceback (most recent call last):
  File "/System/Volumes/Data/home/aszek/tmp/marimotest/notebook.py", line 12, in <module>

    return self._accessor.stat(self, follow_symlinks=follow_symlinks)
PermissionError: [Errno 13] Permission denied: '/System/Volumes/Data/home/pyproject.toml'

As far as I understand it tries to recursively look for pyproject.toml moving up the directory tree, however it eventually hits a folder sufficiently high up to generate a permission error.

Putting an empty pyproject.toml in the same folder as the *.py file is of course a workaround. But it would be nice if marimo worked just to run the *.py file; I don't want or need any additional configuration nor should I have to create a fake one.

Will you submit a PR?
