fix(ios): forceShow to display toast but trigger event until tapped

[erisu]

Motivation and Context

I believe the purpose of implementing forceShow on iOS was to provide the same feature and functionality that already exists on Android. The behavior of the feature should have been identical.

The goal of this PR is to correct the behavior of forceShow so that it aligns with Android.

Original ticket and PR references: #107, #276

While the changes might seem breaking, the original intent of the implementation was not fulfilled. This update will be included in the next patch release, as the current behavior is unintended and buggy.

Description

When the app is in the foreground and forceShow is true, the notification toast should appear in the notification drawer. The on('notification') event should be triggered only when the user taps or clicks on the notification toast.

The iOS documentation has been updated to align with Android's behavior. A comment stating that the UNNotificationDefaultActionIdentifier event is called when the notification is clicked has been removed as this does not follow Android's behavior.
