### Is your feature request related to a problem? Please describe:

I'm not able to deploy a [remix](https://remix.run/) app to Amplify.

Not sure if I can manually edit the build settings to get around this though?

### Describe how you'd like this feature to work

Allow for remix framework apps to be deployed as easily as NextJS apps.

Start by reviewing Amplify Hosting's frontend build handling and the documented build settings, then compare the existing NextJS deployment path with Remix's deployment requirements. Done means a Remix app can be deployed through Amplify Hosting as easily as a NextJS app; the issue does not identify files or tests to run.
