fix: remove missing setup_js_workspace_action reference in npm_install

Fixes CI build failure by implementing a simplified npm_install rule
that doesn't depend on the removed setup_js_workspace_action function.

The npm_install rule now uses a direct shell script approach consistent
with the simplified js_component implementation.
