(feat) use satisfies operator if possible

when creating SvelteKit files

@dummdidumm I'm curious as to what the rationale behind this change was. Why is the satisfies operator preferable?
It seems like this is just more verbose and more exotic than the simple e.g. export load: PageLoad = .... What's the advantage?

[dummdidumm]

The advantage is that for the generated ./$types we have to generate the types only once and not regenerate them if you update your load function. Also once we persuade the TypeScript team to implement this for functions, too (microsoft/TypeScript#51556), it will look way nicer.

export function load (..) {
  ..
} satisfied PageLoad

It's exotic to you right now, because this is a new feature, but I'm sure you'll get used to it in no time.

Ah okay, that makes sense, thanks.

Yeah, that would make it look a lot better.
