Integrate Svelte 5

[nfacciolo]

Svelte 5 is released since october 2024.

When do you think it'll be integrated with Symfony ux ?

I saw someone has delivered a pull request but it's still a draft:

#2288

Hi,

Yes, @ChqThomas started a PR at #2288 at the same time, unfortunately:

1. AFAIK there is still BC issues, we can't drop Svelte 4.x support in a Symfony UX minor release
2. More importantly, as described in [Svelte] Svelte 5 support #2288 (comment), the CDN version of Svelte 5 (the one we use for AssetMapper/ImportMap) was not working at all, but maybe it's not the case anymore

Do you want to help move things forward?

Thanks!

Hi!

Quick update: on the Svelte side, things haven’t moved much on the CDN version support 😔 sveltejs/svelte#13186

I'll mark the PR as open for review
