currently blocked on Data Wrangler's jupyterVariableViewers command contribution needing to handle cases with a debug session and no notebook.

verification steps:

1. Install Python, DataWrangler and Jupyter pre-release extensions
2. Create a .py file with the content below and set a breakpoint on the last print line
3. Debug the file (not in the Interactive Window)
4. When the breakpoint is hit, navigate to the variables view in the debug panel, right click df, and open the data viewer
5. Ensure Data Wrangler's data viewer is opened

import pandas as pd

# create a dictionary with sample data
data = {
    "name": ["Alice", "Bob", "Charlie", "David"],
    "age": [25, 30, 35, 40],
    "gender": ["F", "M", "M", "M"],
}

df = pd.DataFrame(data)

# print the dataframe
print(df)

Does this count as the viewer opening for step 5? I'm in a venv with just pandas installed.

it is being delegated correctly, we can just make that a new issue for DW
