Potentially fixes#9012 by disabling prefetch for all Next.js `Link`
component usage.
With prefetch left as the default and _on_, there were cases where the
prefetch could fetch stale data for Edit routes. Then, when navigating
to the Edit route, the data could be stale.
In addition, I think there is some strangeness happening on the Next.js
side where prefetched data might still come from the router cache even
though router cache is disabled.
This fix should be done regardless, but I suspect it will solve for a
lot of stale data issues.
