Jupyter notebook requires enabling deno in settings.json to disable TS even when deno.json exists

[dsherret]

Describe the bug

I have a folder with only a jupyter notebook in it and a deno.json. In this folder TypeScript is still giving diagnostics.

I can fix this by adding a .vscode/settings.json file with { "deno.enable": true } in it.

To Reproduce

1. Create a folder with only a deno.json and a report.ipynb file
2. Observe typescript diagnostics exist and auto-complete gives two entries for everything.

Expected behavior

TypeScript should not be showing diagnostics.

Versions

vscode: 1.87.2 deno: 1.42.1+86bc7a4 extension: 3.36
