Deploying micro frontend using webpack's module federation

We are attempting to deploy an individual web app that is exposing only a webpack module federation remote file without an index.html. The deployment is failing cause the Azure resource is looking for a default index.html file in the artifacts directory, which the micro frontend does not produce.

```bash
---End of Oryx build logs---
Try to validate location at: '/bin/staticsites/491071d9-a6bd-4308-ad0a-c3868e782251-swa-oryx/app/dist'.
Finished building app with Oryx
Failed to find a default file in the app artifacts folder (dist). Valid default files: index.html,Index.html.
If your application contains purely static content, please verify that the variable 'app_location' in your workflow file points to the root of your application.
If your application requires build steps, please validate that a default file exists in the build output directory.

For further information, please visit the Azure Static Web Apps documentation at https://docs.microsoft.com/en-us/azure/static-web-apps/
If you believe this behavior is unexpected, please raise a GitHub issue at https://github.com/azure/static-web-apps/issues/
Exiting
```

Steps to reproduce the behavior:
1. Create react app to host remote for webpack module federation
2. Use a similar webpack configuration
```js
plugins: [
new container.ModuleFederationPlugin({
name: 'profile',
filename: 'remoteEntry.js',
remotes: {
list_user: `list_user@https://{static_app}.azurestaticapps.net/remoteEntry.js`,
},
shared: {
react: {
singleton: true,
requiredVersion: deps.react,
},
'react-dom/client': {
singleton: true,
requiredVersion: deps['react-dom'],
},
},
}),
],
```
*The root file for this deployment will be `remoteEntry.js` and no index.html is produced.*

**Expected behavior**
Azure Static Site that has a Javascript file as a default file.
