Description

🐛 Bug

When you use the new union syntax (str | None) papermill does not think that this is a parameter and it does not appear when calling pm.inspect_notebook or when calling papermill --help-notebook

Contributor guide

Research direction
Examine how papermill parses parameter cells and update the parameter extraction logic to recognize PEP 604 union syntax (e.g., 'str | None').
