Add a when clause to the contributed explorer view such that it is only activated when the workspace has a package.json file

[tristan957]

As you can see below, I don't have a package.json file in my workspace. I am working in a Python project. This extension is still contributing its view however.

Would it be possible to have the extension only contribute its view when a package.json is found at the root of the workspace?

This feature is talked about here microsoft/vscode-java-test#793 (comment).

I am little confused where that view gets contributed when reading the package.json

@alexr00 is this a regression from when the when clause was changed so that it is always visible in the Views menu?

[alexr00]

Since the npm view is hidden by default, and because #104591 I removed the package.json check. I can re-introduce the package.json check and have it search all folders instead of just the roots of the workspace folder if we want to fix this.

After discussing with @egamma we decided to add the package.json check back in and make it more comprehensive.

Works but this search is very expensive!

I see you added a 1s timeout, thanks! Always be careful with triggering a search on startup
