Implement Monetization

Docs: https://discord.com/developers/docs/monetization/overview

I've tested this code to the best of my ability, i.e., only the pagination for the list entitlements endpoint is untested and I wasn't able to get entitlement events to work, they might only work with real subscriptions 🤷🏼

forgot to implement the premium required action interaction response :')

thanks for the pr :)

i've looked at the code for common and gateway for now, i will look at rest and core later.

would be good to also add the error codes documented in this pr: discord/discord-api-docs#6499

[lukellmann]

looking at core will follow tmrw

also some tests fail, now that entitlements is no longer optional in the interaction object, updating the test data should be good enough

With an empty array or should I write mock data?

empty should be enough, do as you see fit
