feat: use @clack/prompts

[Rich-Harris]

Thought I'd have a go at using @clack/prompts to make the create-svelte experience slightly more polished.

Is there a way to test this locally and see what the new experience is like?

[Rich-Harris]

yes, just run bin.js

../kit/packages/create-svelte/bin.js

I like the change! The "select what you want" for the optional things instead of a chain of yes/no is better, even if it requires some unlearning for existing users.
Is there anything fancy we want to add while we're at it? Ascii-Svelte-logo or sth like that.

I thought about it but it feels a bit gimmicky and doesn't work with very narrow terminals — I think we should respect the user's screen real estate as well as their time by making everything as compact and direct as possible

I can't select options.
How can I select them/all?
Some more instruction on how to select is helpful.

[shinokada]

Ok, I found it out. You need to press the space to select it.

@shinokada Literally tracked down this PR to ask about this as well :) Definetly needs more clear instruction here @Rich-Harris
