Ability to access store context when using composable stores

[Fl0r14n]

What problem is this solving

There is no way to access the plugins when defining stores using composable stores, though they are present when using the store

Proposed solution

const pinia = createPinia().use(({ store }) => {
store.router = markRaw(router)
})

const useMyStore = defineStore('MyStore', storeContext => {
const {router} = storeContext
console.log(router)
return {router}
})
