Enable Data Table Renderers to work on github.dev and in the web version of vscode IDE

see docs: https://code.visualstudio.com/api/extension-guides/web-extensions

& Microsoft VSCode Notebook Renderers that currently work in a browser:

Current Pyolite notebook raw JSON data output due to lack of rich data table renderers in that vscode IDE context:

Looks like this works after adding browser entry point to package.json & using https://github.com/microsoft/vscode-test-web to test data table renderers extension locally:

ok. that fixes web extension loading ...

confirmed that those changes work in Code Spaces:

However, those sample notebook files are downloaded in vscode web editor on https://github.dev and https://vscode.dev because the constructed path of example notebooks is an http based Url, not a file in web IDE. So, vscode.open we use to load those example notebooks results in a file download and doesn't open it in vscode editor tab.
