Goals

1. Hydration errors are basically impossible to debug in production because there is no stack trace or anything to work with, Next should print the hydration error component stack in the console (exposed as errorInfo.componentStack in onRecoverableError)

Non-Goals

No response

Background

React exposes the hydration error stack as second argument of onRecoverableError, errorInfo.componentStack (i found about it in this tweeet), Next should print that stack together with the error message

Docs about onRecoverableError: https://legacy.reactjs.org/docs/react-dom-client.html#hydrateroot

Related discussion: #36641

Proposal

Add the component stack to the default onRecoverableError here
