V2_MetaFunction type incorrect for error boundaries

[kentcdodds]

What version of Remix are you using?

1.14.1

Are all your remix dependencies & dev-dependencies using the same version?

• Yes

Steps to Reproduce

1. Configure remix for the latest meta and error boundary features
2. Make a route that throws an error or response in the loader
3. Add a meta export that uses the V2_MetaFunction generic and pass <typeof loader>
4. Use data.whatever and see that the types are totally cool with that
5. Hit the route with the thrown error and see the runtime exception.

Expected Behavior

The types should warn that the data property could be undefined.

Actual Behavior

Meta functions are called for error boundaries so the data property that's passed could be undefined. The types don't allow for this currently.

I made a PR which may help explain what I need: #5787

Fixed by #6231, will be available in the next release (likely 1.17.0)
