[Fix] Update RaiderIO hooks

[ArthurEnglebert]

RaiderIO addon had different names; one was RaiderIO, the new packaging is "Raiderio", notice the difference in the end.

RaiderIO/raiderio-addon#196 here is the issue wrongly submitted to RaiderIO devs
https://github.com/RaiderIO/raiderio-addon/blob/develop/core.lua#L6234 here is the actual creation of the problematic frame

This also comes from the fact that addon existence is checked via "strlower" addon name while the frame lookup is case sensitive

function AS:CheckAddOn(addon)
	return AS.AddOns[strlower(addon)] or false
end

I don't know myself a lot of lua, so this fix might look ugly & probably better way to refactor the whole code base, but at least, this pr will shine some light on it
