Rule Ts incorrect

The `rule.js` recently refactored the `rule.event` property to `rule.ruleEvent` (80e84b3ada7df7fca20aba21e37d8b5ee4257023) but there were no corresponding updates to the types when using the types accessing the property directly does not work as expected.

Should the type use `rule.ruleEvent` or should it use accessors for the event?

js & ts are not my speciality but i think the 'event' property of the interface needs to have a `get function` & `set function` that are actually the `getEvent` and `setEvent` functions.

首先檢查 rule.js 以及公開 rule.event 屬性的型別定義。將重構後的 rule.ruleEvent 屬性與 issue 中提到的 getEvent 和 setEvent 存取子進行比較，然後驗證哪種形式允許透過型別直接存取屬性。當型別與執行階段行為一致，且直接存取能如預期運作時，即表示完成。
