2.0.0 docs missing migration guide for ref changes

https://v2.solidjs.com/migration/from-solid-1

<div ref={()=>{
  console.log(getOwner()) // 1.x(true)   2.x(false)
 }}>
</div>

solid 1.x ref is owned ( https://s.olid.uk/id/qSQe8ZJ6QRyiJTtdfQDNrQ )
solid 2.x ref is non owned ( https://s.olid.uk/id/KyofyVLqQC2upVRrxbCTYw )

In 1.x we could register cleanup in the ref callback, but not in solid 2.x
no ownership is documented in the docs for 2.x . but the migration guide is not addressing it.

it should show the migration path for ref changes.

I assume that we now requires an higher order component wrapper

also what is the reason that ref has no owner?

Comienza con la guía de migración en https://v2.solidjs.com/migration/from-solid-1 y compara su cobertura actual con los ejemplos de callbacks de ref del issue. Documenta la ruta de migración de Solid 1.x a 2.x para la ownership y la limpieza de ref, incluido el motivo del cambio de ownership y si el enfoque de wrapper propuesto es necesario.
