[Web/WebGPU] Can't append execution provider: JS (v1.15.0)

[xenova]

Describe the issue

When attempting to use the webgpu backend, I get the error:

JS execution provider is not supported in this build. 
Error: Can't append execution provider: JS
    at t.setSessionOptions ...
    at t.createSessionFinalize ...
    at t.createSession ...
    at t.OnnxruntimeWebAssemblySessionHandler.loadModel ...
    at async Object.createSessionHandler
    at d.create

To reproduce

This happens for any model when running with webgpu. See my previous issue (#15719) for steps to reproduce, but just add webgpu as a backend.

Urgency

I might just be missing a simple flag/option, but since the docs aren't up-to-date, it's quite difficult to find what I need to do.

docs are being worked on...

the latest way to consume webgpu is using ort.webgpu.min.js , or

import * as ort from 'onnxruntime-web/webgpu';
