Fix deprecated Matplotlib grid argument in AEPsych tutorial (#397)

Summary:
### PR Description:
This pull request fixes issue #372, which involves the use of the deprecated `ax.grid(b=None)` in the AEPsych tutorial. As per the [Matplotlib 3.9.0 API updates](https://matplotlib.org/stable/api/prev_api_changes/api_changes_3.9.0.html), the `b=None` argument has been removed, causing a `ValueError` in recent versions (3.9.0 and above).

To address this, the `b=None` argument has been removed from two lines in the notebook, ensuring compatibility with Matplotlib 3.9.2 and higher.

The database-related error has already been resolved in PR #295, so no further changes are necessary regarding that.

This PR resolves the compatibility issue and ensures the tutorial runs correctly with the latest version of Matplotlib.

Pull Request resolved: #397
