Josh Story 035a12ea8e [dynamicIO] Document client component remediations for sync IO (#79787) ...

When you use sync IO in the client in a way that needs to be fixed we
currently still just provide you with the explanation for server
components. The fixes when sync IO happens in the client are not the
same as when they happen in a server component so this update adds
client specific documentation for these situations.

Namely, the key difference is that on the server you can add caching
through "use cache" and this is not available to you in the client. sync
IO in general is (going to be) allowed in client components broadly as
long as Next.js has a fallback UI to prerender. This means that "fixing"
sync IO access in the client will usually be solved by wrapping in a
Suspense boundary. The alternative is to move the sync IO out of render
or move it to the server where it can be cached.
