refactor: reduce the unnecessary use of markRaw

[Mini-ghost]

Is it necessary to use markRaw for actionSubscriptions and subscriptions here?

pinia/packages/pinia/src/store.ts

Lines 258 to 259 in d710cb8

	let subscriptions: SubscriptionCallback<S>[] = markRaw([])
	let actionSubscriptions: StoreOnActionListener<Id, S, G, A>[] = markRaw([])

I have examined the context of the source code, and it appears that actionSubscriptions and subscriptions are never potentially converted to proxy at any point in the code. Additionally, users do not have access to these arrays. Given this information, is it still necessary to use markRaw for them?
