typescript test workspace issue

Description

I planned to use the typescript test workspace to learn about latest practices for bazel+typescript+grpc.

I noticed it is using ts_library but had read that ts_project is preferred for new code so I was going to try converting.

But before I got to that...

I changed nodejs_test to nodejs_binary and ran bazel run //:test_main. All good.

I wanted to know how the import path was resolving (js_lib/js_lib_pb/demo_pb). I added a line to console.log(demo_pb) and could no longer run without getting an error: Cannot find module 'js_lib/js_lib_pb_demo_pb.js. Seems like the import can get past the typescript compiler but the lib js isn't actually resolved at runtime?

Also, I was wondering how IDE (e.g. VS Code) is supposed to know how to resolve the imports.

From Slack:

• Works on 3.x.x
• Likely related to prefix stripping not working in ts_library like it does with js_library
• Probably needs a fix in rules_nodejs and it’s likely me that missed this in the original stripping PR
