test(nodejs): Port nodejs module tests from E2E to integraton (#867)

Replaces the existing nodejs module end-to-end tests with integration tests that don't require preinstalled environmental dependencies.

- Moved the tests to the same file as the module they test
- Created a render_module utility function for rendering modules within tests
- Removed Node.js installation during CI setup
- Add Shell to Context to allow for tests to not run shell-specific code
