Fix Alpine setup to patch transformers backend directly

Browse Source 
Instead of creating a stub onnxruntime-node module, patch the
@xenova/transformers backend file to skip the onnxruntime-node
import entirely and use only onnxruntime-web.

This prevents the "Cannot read properties of undefined" error
when the library tries to use the Node backend in a Node.js
environment but only has the web backend available.
