Duplicate onDestroy method description

[loky-lp]

As you can see from this screen the "Schedules a callback.." section is written twice, with the first one still having the type definition, but other method in the same page don't.

I've immediately jumped to fix this but when i was going to create a PR i saw this:

If this is a documentation PR (i.e. changing content within apps/svelte.dev/content/docs), then this is the wrong repository to make those changes. The content in this folder is synced from other repositories. Therefore, these changes should be made in their respective repositories (at https://github.com/sveltejs/svelte or https://github.com/sveltejs/kit, or example).

I can't figure out this sync mechanism, since the source file in the https://github.com/sveltejs/svelte repo has this > EXPORT_SNIPPET: svelte#onDestroy that I don't understand how it's used, since is the only appearance that EXPORT_SNIPPET makes in the entirety of the repo

The source file at https://github.com/sveltejs/svelte:
https://github.com/sveltejs/svelte/blob/7be3afb3a642d1654a4b96ddfa3d6239a8cf1a6b/documentation/docs/06-runtime/03-lifecycle-hooks.md?plain=1#L46

EXPORT_SNIPPET inserts the declaration of that module export (source); that should be the JSDoc and the type signature.
The JSDoc has the same content as the following Markdown text.

Given that EXPORT_SNIPPET appears to be completely unused otherwise, it probably should be removed 🤔

Perhaps this issue should be moved to https://github.com/sveltejs/svelte then

There's also sveltejs/svelte#13711 already - we need to decide how we want this to work and which end(s) we want to address this on.
