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?

https://v2.solidjs.com/migration/from-solid-1 の移行ガイドから始め、既存のカバレッジを issue 内の ref コールバックの例と比較してください。ref の所有権とクリーンアップについて、Solid 1.x から 2.x への移行パスを、所有権が変更された理由と、提案されたラッパーアプローチが必要かどうかを含めて文書化してください。
