Update components

[borsuczyna]

Hey, I simply updated Message:update code to update components, I think you should add this:

function Message:update(data)
	return self:_modify({
		content = data.content or null,
		embed = data.embed or null,
		components = data.components or null,
	})
end

greetings!
