[SKU] Implement Subscription Events via API

[phgrandi]

Currently, Discord has introduced a new paid subscription system without providing a REST API endpoint for developers to receive notifications when a user subscribes or renews their subscription. This limitation hinders our ability to seamlessly integrate subscription data into our applications.

I propose the implementation of a feature that allows developers to receive subscription events via API. This enhancement would significantly improve the user-developer experience and enable us to better utilize subscription data in our applications.

Can't you just list entitlements on a regular scheduled job? Alternatively, if you have a simple gateway bot to receive the events, you'll get real-time notifications. Otherwise, Discord would have to send events to you somehow.

You receive an ENTITLEMENT_CREATE event when a new entitlement is granted for a user of your app. Please see the docs for more details: https://discord.com/developers/docs/monetization/entitlements#gateway-events

This is asking for a POST-like interface similar to interaction URLs or incoming webhooks.
