Enable node typings if file starts with node shebang

• VSCode Version:
• OS Version:

Steps to Reproduce:

Here is intellisense working correctly for a node script in a project:

Here is another screenshot showing the support not working for a global script that does have a project:

As node.js is a perfectly valid choice for scripting, and has no need for verbose project structures to work, the lack of support is a bug.

Start by reproducing the reported difference between a project script and a global script that begins with a Node shebang, using the screenshots as the expected comparison. Trace how the TypeScript language service identifies Node scripts and confirm that the fix enables Node typings and matching IntelliSense for the global case.
