Type helper: PropsWithChildren

[Hugos68]

Describe the problem

I often catch myself creating the same helper in nearly every Svelte project:

interface PropsWithChildren<T extends []> {
  children?: Snippet<T>;
}

And using it like this:

interface Props extends PropsWithChildren {
    ....
}

const props: Props = $props();

Typing the same code over and over is a waste of time.

Describe the proposed solution

Svelte could export this helper as a first party type utility.

React, although not known to have done everything best, does have this utility and I use it whenever I have any React project

Importance

nice to have

+1, adding PropsWithChildren as a first-party type utility would be nice indeed. I have a PR prepared and ready to submit whenever the team decides to move forward with this.
