Match `form().pending` to `$effect.pending()`

[hyunbinseo]

Describe the problem

I know runes are different and start with the $ sign.

Still, it seems weird that these basically do the same thing — returning pending promises/submissions as number — but have different syntax.

• $effect.pending()
• form().pending

When using await in components, the $effect.pending() rune tells you how many promises are pending in the current boundary

https://svelte.dev/docs/svelte/$effect#$effect.pending

/** The number of pending submissions */
get pending(): number;

<button disabled={!!modify.pending}>save changes</button>

https://svelte.dev/docs/kit/@sveltejs-kit#RemoteForm

Describe the proposed solution

Convert form().pending from a getter to a function so that it matches the stable Svelte 5 convention.

Thank you for the suggestion. Although they happen to have the same name and similar behavior that is not a reason to align them - therefore closing.
