Add a onHighlight prop to Command.Item

[CNSeniorious000]

I want to run some callback (like preloding) for command items.
For now I can only do this with an ugly hack like this:

  <Command.Item asChild let:action let:attrs>
    <!-- eslint-disable-next-line no-unused-vars -->
    {@const _ = (browser && attrs["data-selected"] && preloadData(item.href))}
    <a href={item.href} use:action {...attrs} class:selected={attrs["data-selected"]}>
      {item.text}
    </a>
  </Command.Item>

Yes I was struggling with this too. I have a search bar with coordinates that are shown in a map. I want to change the map dynamically while navigating the items list. It would be nice if that prop is added.
