Autocomplete {#snippet _} when within a Component

[pauldemarco]

Description

Here is a Component Header that takes a snippet title as a prop:

// Header.svelte
let {title}: {title: Snippet} = $props();

It is used like:

<Header>
    {#snippet title()}
        ...
    {/snippet}
</Header>

Proposed solution

It would be nice if the {#snippet _} could autocomplete for all snippets that the Component takes:

<Header>
    {#snippet <Autocomplete shows all my snippet options>}
        ...
    {/snippet}
</Header>

There is autocomplete already but with a big caveat, it doesn't work when the name is empty because of #1302 (comment).
