Docs: next/link component - remove note about on hover

[dannytlake]

What is the documentation issue?

The documentation for prefetch of the next/link component references behavior about prefetching on hover, see the documentation for when prefetch={false}. There is no documentation on how hover will impact prefetching for if prefetch={null} or prefetch=true

I don't see any actual implementation of the Link component reacting to hover events, so I think this documentation is out of date, especially since the current behavior of Link will either prefetch some level of data (depending on what you've set prefetch to, either null or true), or, it will not prefetch at all (by setting it to false).

Is there any context that might help us understand?
