Description

Note: this PR is targeting @zchsh's branch to add the error-view package. The PR

import { VersionedErrorPage } from '@hashicorp/react-error-view/versioned-view'

export default VersionedErrorPage

I opted to use pages/_error here instead of pages/404 as the page renders differently depending on the URL, and so static generation of the 404 page doesn't really make a lot of sense IMO. The alternative is to SSR it one way and do some client-side munging to render it differently after the initial hydration, at which point why not just SSR?

✅ This looks great to me! On board with using pages/_error 👍
