Steps to Reproduce

1. Call IDiscordRestChannelAPI#GetChannelMessageAsync with message id of a Discord's auto mod action
2. Inspect the returned Result's Error

Expected Behavior

The method to return a successful Result<IMessage> with a valid Entity.

Current Behavior

A Result<IMessage> with the Error property set to ExceptionError is returned.

[VelvetToroyashi]

This is due to Automod using an undocumented embed type auto_moderation_message.

[Nihlus]

Could one of you open an issue on the docs repo for that type?

[VelvetToroyashi]

They have no intentions on documenting this, as AutoMod is "in beta and still being finalized" if memory serves.

[VelvetToroyashi]

That and embed types being deprecated, as far as the documentation is concerned.
