Children slot forwarding causes recursion svelte-5 migration

[machycek]

Describe the bug

When you have a simple component that is forwarding a children slot in Svelte 4 and migrate to Svelte 5 it doesn't work correctly. It causes infinite recursion where snippet is calling itself.

#14127 / #14090 has already fixed named snippet and works really well, we just missed children prop.
