children prop has a default type unknown

[theetrain]

Describe the bug

Related to #2303

The children prop doesn't seem to have a default type of Snippet.

Reproduction

1. Create a new file A.svelte containing:

<script>
  let { href, children, ...rest } = $props()
</script>

<a href="/test">{@render children()}</a>

2. Observe the type error on children():

This expression is not callable.
Type '{}' has no call signatures.

Expected behaviour

children is given a type Snippet since it's a reserved name/symbol.
